There is nothing so frustrating as trying out an unfamiliar design system in a game and having your numbers not match the samples.

GURPS: Traveller Interstellar Wars I am looking at you!

I can't get my numbers to match their numbers for the Iiken class scout-courier.

I can get very close, but not quite.  I'm using the number of systems they say they used but I end up with seven dTons of extra cargo space; 5.6 tons heavier empty and 21.8 tons heavier loaded which is doubly wrong because 7 extra tons of cargo space should make it 35 tons too heavy all alone, so it should be 40.6 tons overweight if all the assumptions were the same.

ISW is another example of the ship rules changing things so that the feel is altered.  It doesn't feel like Traveller anymore.

On the plus side, it's sure an interesting part of the Traveller history and set so far in the past of the more normal Third Imperium that maybe it shouldn't feel like Traveller.

Update:

The feel of the ship design comes pre-disrupted by the change in fuel requirements.  GURPS fusion power plant don't consume tons and tons of liquid hydrogen every month.

Dunked the S&W.


Went to Waffle House, because it's traditional after doing gun stuff.  Then drank some beer in the back yard around our fire pit.

See how fast Shi Shu can go fetch?


The water... changed...


So did the revolver!









Electrolysis isn't going to restore a rusted gun to pristine shape, but it will change all of the pitted rust into steel again.  It's a good way to make sure the rust pits aren't hiding some corrosion that oil and a brush might miss.  All in all I am happy with how it came out.

History of Dottie

$

Dottie has seen almost as many changes as Kaylee.


Dottie's name derives from a line in the movie, "Armageddon". The amateur astronomer who discovers the planet killing asteroid wants to be able to name it after his wife, Dottie, because she's a life sucking bitch from which there is no escape.


Dottie is a "franken AR", her parts are from everywhere. The lower is Spike's Tactical, the lower parts kit is CMMG. The upper is a DIY with a Bison Armory barrel, and YHM folding front sight with an 5/8-24 A2 flash-hider and KAC 600m folding rear.

I'm using a Magpul MS3 Single QD sling and Surefire X300 that I share among the go-to home defense guns.  BUIS is a Knights Armament Corporation 600m Micro Flip-Up.





18MAR08
As she was first assembled: Anvil lower, Cardinal upper and 16" mid-length barrel, YHM Phantom 5C2 flash-suppressor, YHM folding front sight, YHM lightweight 4-rail, Knight's Armament Corporation 600m folding BUIS, UTG rail covers, commercial Gen 1 M4 stock, Magpul MIAD pistol grip and L3 EOTech 552.A65/1 optic.

29MAR08
To get a better picture at longer ranges I added a LaRue PoBoy 2.5x optic.

04JUN08
The commercial stock was both too long and was contributing to the gun being nose heavy. I changed over to an A2 fixed stock.

28JUN08
Based on The Lovely Harvey's choice of a Troy Medieval flash-hider for her Cheyenne, I selected their Medieval Muzzle Brake for 6.8 for Dottie. This change also allows me to mount a standard bayonet, in this case an M9.

25OCT08
The A2 stock just didn't fit the character of the 16" middy upper, so I replaced it with a Mil-Spec Magpul CTR stock. I also added a GG&G "Sling Thing" to the left side rail.

29OCT08
The YHM-9634 lightweight 4-rail with the UTG rail covers was like gripping a coffee can. Marv ordered a YHM smoothie free-float tube for his 6.8 build and I followed suit.

08JAN09
While the smaller diameter was nice, the smoothie tube got HOT when firing. Based on an article I read on Arfcom, I wrapped it with 550 Para-Cord.

Because of Geff's desire to have a fully noncompliant AR in black and because we couldn't order any color but OD green due to the post-election panic buying, I swapped him my black Magpul stuff for the OD green he ordered.

11JAN09
Because I had the lightweight 4-rail laying around and hundreds of feet of para-cord left over, I started playing around with alternative wraps.

25JAN09
And then mounted them on the gun... The smoothie didn't allow the wrap to go far enough to the rear of the gun and I was still burning myself.

01FEB09
The para-cord was better, but still not what I wanted. Here is an attempt to be happy with Magpul's ladder style rail protectors.

01APR09
The Lovely Harvey needed an optic for her Kevina, she preferred the EOTech and I wanted an Aimpoint Comp M4s so it worked out well.

03APR09
Because this is a SHTF grab gun, it needed a light. This is a Surefire X300.

21APR09
The ladder covers were still not what I wanted, so I tried the Magpul XTM modular rail covers. I also moved the light to be easier to activate.

15MAY09
I really like the XTMs, but I was back to the "gripping a coffee can" problem I had back with the UTG covers. Finally figuring out it's the rails and not what I am covering them with I replace the YHM with a LaRue LT15-9 4-rail.

One drawback is the Aimpoint is now too far to rear for the PoBoy, but that hasn't affected my shooting at 100 yards.

08APR10
I added a Magpul AFG angled fore grip. It's inexpensive so I thought I'd check it out. I rather like it. It does allow your supporting wrist to be at a more natural angle than a conventional handguard and is less obtrusive than a vertical grip.
Right side:
Left side:
Wrist angle:

On the LaRue 4-rail the AFG interferes with the Magpul XTM rail panels. To put the AFG where I was comfortable, I had to remove one section of XTM. In fact, there's no way for the front part of the AFG to put anything on the side rails. The LaRue's bottom rail is closer to the barrel than the top, so there's less room here.

The loss of the third XTM panel bothered me because fingers were hitting rail. It's unpleasant. So I took a teeny lip off the underside of the XTM panel with the Dremel and that leaves enough clearance to get the AFG under it.

I had to move my light from the bottom rail to one of the sides, because of the change in grip angle, this is actually easier than the bottom was.

I took the 'A2' finger stop out of the grip area since, like usual, it was where I wanted a finger instead of between. Even with it reversed.

It doesn't feel at all like I expected it to, but it is more comfortable with Dottie's nose heaviness.

02MAY10
Way back when I had pressure signs from the SSA tactical loads with the Cardinal Armory barrel. I had read that there were things I could do to fix the issue, but just in case those failed, I ordered a new barrel from Bison Armory in June of 2009. It finally arrived last week. Since I am not the sort of person who can leave well enough alone, I swapped the barrels. I like the looks of the heavier contour better.

Contour before:

Contour after:

Plus the new barrel is just slightly longer, letting the bayonet sit on the flash-hider properly!

24-25MAR11
Removed the MagPul AFG, MIAD and CTR.  The AFG was replaced with the XTM panels it originally supplanted.  Standard A2 pistol grip returned to replace the MIAD.  Genuine Colt M4 stock replaces the CTR.  Move the Aimpoint M4s slightly further to the rear to slightly improve balance.  The M4 stuff didn't last long and I reverted to my Magpul parts within a couple of days.


03AUG12
Ditched the Troy Medieval muzzle brake for a Wilson Combat Accu-Tac flash-hider. Dottie is now FULLY non-compliant with the Clinton Assault Weapon ban! The Accu-Tac also has the cannelures for rifle grenades that the Medieval was lacking.





24SEP12

AFG reinstalled, finger swell front strap returned to service on the MIAD and bipod adaptor mounted with bipod.  Full story here.


23DEC12

Displaced is the Anvil Arms lower and the Spike's Tactical Florida Home Town Forum lower in its place.

Replaced the LaRue LT15-9 with a Magpul MOE handguard.

It's astonishing how taking those 6 ounces off the front make it feel like it weighs nothing up front.

This little piece of P-Rail replaces covers one of the slots in the handguard.

The back-side:


The Surefire X300 Weaponlight clicks right onto it.




Zero loss of functionality over the 4-rail, still six ounces lighter.  Actually the light is slightly better placed now than before.


24FEB13

The Magpul Illumination Kit came with a short 3-slot section of rail.

I got curious about what use I could put it to and decided to see if mounting a GG&G Sling Thing there would be comfortable.

It is!


The sling location is similar to where I had a QD socket on the LaRue 4-rail.

Links to Midway USA because they're in the NYFS boycott.

28NOV13

Deleted the AimPoint M4s and replaced it with my hoary old Sight Unit Infantry Trilux L2A2 on a hard to find Tapco mount. A short rail section allows the use of a Harris 1A2 Ultralight bipod.


With the Magpul MS3 Single QD sling and Surefire X300 that's shared among the go-to home defense guns.  I moved the original KAC 600m sight to Kaylee and replaced it with the compact version of the same.  The bipod is actually FuzzyGeff's, and normally resides on his target AR, Olga.  I'm borrowing it to get the SUIT zeroed.


17JAN14

Replaced the battery powered SUIT illuminator with a tritium powered one.  Swapped the Magpul CTR (milspec) stock and H-buffer for a Magpul MOE Rifle stock.  It ups the weight by about a quarter pound, but the balance and cheek weld are much better.  Alas, it costs me an AWB feature though.


12MAY14

Ditched the Magpul MIAD for a Damage Ind A2 ECS grip.  With the narrow back-strap on the MIAD to fit the M12 rifle rack, there's not much difference in feel between the MIAD and an A2.  What an A2 has over the Magpul offering now is it's one piece and doesn't have that odd creaky feeling when the back-strap shifts ever so slightly.  I lose the battery storage though.


04JUN14

Swapped barrels with Valentine.  This drops 0.4 lb. off her and she was such a tubby girl.  Without optics or lights, but with a loaded magazine she trips the scales at 8.6 lb. now.  The front sight is no longer a screwed on YHM a pinned on standard unit sans bayonet lug.  I didn't feel like messing with the muzzle devices, so the A2 style is de rigueur.  Dottie is now has the fewest AWB features of any of the AR's.



09MAR15

Swapped uppers with Valentine, the SUIT stayed with the purple gun.  I'm getting a Primary Arms 4x ACSS scope just as soon as I have the money and they have them in stock at the same time.  Until that day, I will make due with irons.


This is Kaylee.

Kaylee is my first AR-15.  She started life as an attempt to make a clone of an XM177E2.  Unfortunately, I didn't know much about XM177E2's when I started; in fact I thought CAR-15 was the proper designation.  I later made a much more faithful clone of an XM177E2, and then I decided to make Kayee more of an Israeli  carbine.

This Israeli carbine, in fact.



But as time passes, plans change.  Kaylee was entirely too similar to The Lovely Harvey's Cheyenne.  Cheyenne is a clone of an R653-P because Harvey loves the carbine carried by SSG Barnes in the film Platoon.

Because she felt I was stepping on her toes, I changed Kaylee's furniture.  Then did some swapping with some Arfcommers and ditched the carry handle.


What we have here is a Del-Ton carbine kit that I have modified.  The 16" HBAR barrel that came with the kit was replaced with a 14.5" 1:9 lightweight J&T chrome-lined barrel with a Wilson Accu-Tac flash-hider.  The C7 upper has been replaced with an Aero Precision flat-top and KAC 600m folding rear.  The lower receiver came from Anvil Arms, who are no longer in business.  In foliage green, items from Magpul; CTR stock, MOE handguard and Damage Industries ECS grip Bravo Company mil-spec receiver extension.


Complete history after the fold.  There have been a lot of starts and stops along the way while I figured out what I wanted to do with her.  And yes, I give my rifle's girl's names.  And yes, you've seen this post before, it gets bumped and updated as I make changes.


She is named after Kaylee from "Firefly".  She's the second one I built all by myself and the third I had a hand in. Dave's pile of Bushmaster parts was the first one I helped with. Geff's Moose was the first one I built alone because I wanted to take detailed pics of Kaylee's build.

Kaylee, as I mentioned before was supposed to be as close to an XM177E2 as I could make without going NFA. Since I knew that I couldn't get it exact, I dubbed her XM177E3, a "what-if" the carbine program had not resulted in the M4.  My making of Sabrina, a very accurate clone of an XM177E2 and Harvey's making of Cheyenne, a 90% clone of an R653 made me decide to drop the facade of retro from her and make her into something of a late R723 
full M4A1 clone (with a 16" barrel).  I never really wanted a pencil barreled M4gery so I have settled on the Israeli configuration.

16MAR07.
Her baby pictures. The lower and the parts kit.  Interestingly, these are the only parts to have never been replaced (except for the pistol grip).









Freshly assembled. Complete Del-Ton 16" heavy barrel carbine kit, Anvil Arms lower and a DPMS slip-over flash suppressor. The M4 style stock here is commercial diameter. The upper receiver is known as a C7 model. When Canada adopted the M16, they retained many of the features of the M16A1 and combined them with features from the M16A2; in the case of the upper, they kept the simpler rear sight of the A1 and added the brass deflector bump from the A2.





22MAR07.
It did not take me long to start making changes as suited me. I swapped the small round forward assist for a retro tear-drop unit.






The first real pic of the whole gun.







08APR07.
Vintage pistol grip to replace the A2 style. These are called "A1" grips, but are also present on A-Nothing M16s. Also a vintage Colt 20-round magazine.






23JAN08.
Insanity breaks out! I succumb to the fashions of Arfcom and replace my A1 grip with a Magpul MIAD and the C7 upper with a flat-top. The optic is an L3 EOTech 552.A65/1, the back-up iron sights (BUIS) are Knight's 600m.






14SEP08.
Because the optics and BUIS went onto my 6.8x43mm build, Dottie, keeping the flat-top seemed silly, so I put the C7 upper back on. The flat-top was recycled into the carbine that became Kevina.






18JAN09.
The MIAD went to Dottie and I changed the commercial M4A1 style stock to a mil-spec early M4 style. Commercial receiver extensions are about an inch longer than mil-spec and I was sick of setting the stock back a click when I extended it. I figure that these things really have two positions, closed and all the way open to the stop because you will not have time for fidgeting when the SHTF. The A2 grip is back because I used the A1 grip on Bubba's AR.






21FEB09
The return of the A1 pistol grip! This also marks my realization that the SBR I am making has supplanted the retro aspects of Kaylee.





10JUN09.
I changed the early pattern stock to a late pattern M4. There are three two M4 carbine patterns. The early is smaller and more closely resembles the original aluminum stock from the XM177 series, these are also known as "fiberlite" stocks. The middle design has a longer butt and a sling loop in the toe (the commercial stock that came with the kit is this style). The late pattern has a revised sling loop, slightly more pull and better reinforcement along the extension. I changed the conventional carbine handguards for the oval M4A1 style.

At this point, she is truly almost the what-if I set out to make. What if in the course of carbine development the special forces community had insisted that the M16A2 rear sight was needlessly complicated? What if they had lengthened the barrel to 13.5" and retained the moderator instead of going for 14.5" and normal flash-hider so they could use a bayonet?  What if the moderator had been made into an effective sound suppressor?  What if the use of optics and development of the flat-top upper had died in the womb? What if they had continued the previous designation scheme? So here we have an XM177E3, this is the carbine that Twilight 2000 would have in its original timeline.





I would like to point out that the XM177 series had no bayonet lug because the moderator was both too large a diameter and too short for the M7 bayonet. The lug is retained here just to have all the features banned by the Clinton Assault Rifle Ban.

01JUL09
Final change, M4 profile barrel.  The Army was very keen back on the change from XM177E1 to XM177E2 to be able to equip the carbines with M203 grenade launchers, but not to make a special version of the M203 for carbines. On the M4 (and here) this resulted in a small area of the barrel in front of the front sight base to be rebated for the barrel clamp of the M203.  This change also drops a full eight ounces of weight from the front of the gun, where it's most noticeable.






UPDATE

GURPS stats for my Twilight 2000 conversion.  Since it is finally adopted, the X is dropped from the designation and the E is changed to a nothing for the first issue.  Remember, the original timeline did not include Desert Storm, so the impetus to create the M4 carbine was not present, especially with the military budget firmly committed to a war against the Soviet Union as opposed to counter insurgency.  There was a special forces requirement for a carbine that had been festering since the Vietnam war, however.

The Colt M177 is a shortened M16A1 upgraded with many features of the M16A2 specially tailored to the needs of Special Forces troops in the US military and based on experience from the IDF.  The 13.5" barrel is rifled for NATO ammunition and is equipped with a threaded detachable TL7 baffle sound suppressor (High Tech, p. 158-159) giving -2 to hearing.

31JUL09
I changed the front sling swivel over the the current USGI side sling mount.  I had originally bought it for Harvey while she was deciding what sling would suit her best for Kevina.  The main reason I decided to use it is that I was not happy with how the sling swivel rivet I set had come out.  It was solid, but cosmetically ugly.









04AUG09
I ditched the heavy barrel with the express purpose of shedding weight.  Weight that I seem to have added right back on with the late M4 stock, side sling adaptor.  What made me realize this was recycling the heavy barrel into Brunhilda and having her come out lighter than Kaylee!  So I have deleted the slip-over flash-hider in favor of a standard M16A2 unit.  It ruins my what-if story but makes the her so much handier and shootable.  In accordance with the modernization I put a small round forward assist back on her.  Talk about a cosmetic part!  I have never had to use one operationally.





15SEP09
Changed the furniture over to Colt stuff.  Also changed the sling to a lightweight M4 item.  The colt stock fits this tube better and the handguards are the double heatshield style.




I wonder if I am done this time.  There's always a temptation to spend the $200 on registering her as an SBR and cutting the barrel back to 14.5" and putting a flat-top and optic to replace the C7 upper. 

30Nov09
The double heat shield handguards don't fit well.  They don't engage the teeth on the barrel nut very well and will rotate a small amount.  That makes the gun unpleasant to hold and affects my consistency.  So I have replaced them with a set of Israeli contract 6-hole CAR type handguards.  The M4 stock doesn't look right with the narrow grips, so I used my Colt fiberlite.  At this point she very much resembles a late production R723.





04DEC09
Changed the flash-hider to a birdcage and the pistol grip back to an A1.  It's looking more like an Israeli parts gun every day.  Makes me want to get the elastic handguard covers and sling the Isrealis use.  Like these.





01MAR10
Kaylee and Cheyenne looked entirely too much like each other.  Far be it from me to mash on Harvey's toes; I have been accumulating M4 parts for a while.  Kaylee is now an M4gery, complete with flat-top and genuine Colt detachable carry handle.  Bravo Company's double heat shield handguards fit better than the Colt too!  





The next step is an optic.  I am torn between an Aimpoint Comp ML3 (2 MOA) in a La Rue mount or a Comp M4.  The ML3 is cheaper, but the M4 uses the far more common AA size battery instead of a DL1/3N.  With the optic do I keep the carry handle as a spare and swap it for the optic should something go wrong or get a dedicated folding backup iron sight (BUIS).  The Marines swap the handle.  The Army uses a BUIS from Matech.  It's known to be fragile and expensive.  Troy makes an excellent rear sight, as does Knight's Armament.  Decisions, decisions!

29JUN10
Or I could just put her back into the R723 configuration.  Honestly, I am more comfortable with things this way than as an M4gry.  I don't care for the look of the detachable handle and I have never been a big fan of the A2 rear sight.





Maybe there's space in my heart for an M4 or M16A4 clone; but Kaylee is not one.

19JUL10
She's now wearing genuine IDF accessories!  Eventually, she will be Form 1'd and I'll get a 14.5" pencil barrel on her.  This is honestly the happiest I have been about how she's been dressed since the very first day I put her together.





The magazine holder is because Israeli citizens and troops outside of a combat area are not allowed to have a loaded mag in the gun, and this is a handy way to have one nearly ready.


13FEB12
A little more genuine!  Got the tax stamp and added a 14.5" pencil barrel.  The Trilux is a bonus addition.



04JUL12
I added an authentic IDF touch to her.  A Lone Star Ordnance pistol grip.  You see these on lots of IDF guns, it's just interesting that something made in relatively small numbers in San Antonio, Texas is relatively common accessory in Israel.






 One neat thing about a 14.5" barrel on a carbine is the bayonet fits properly.


06MAR13

Ditched all the IDF stuff and changed over to Magpul furniture; because it resembled The Lovely Harvey's Cheyenne too much.  CTR, MIAD and MOE in foliage green.


05APR13

Stumbled into a deal where I could get a flat-top upper for no out-of-pocket cost for me!  Changed the flat slip ring for a delta-ring and slapped on a YHM-9680 folding rear sight (both collecting dust in the parts bin).  Kaylee is now Mini-Dottie!


31DEC13

Although the Aimpoint has been mounted on Kaylee instead of Dottie for a while, this is the first time I thought to update her build saga.  Also pictured are the Surefire X300 and Magpul sling that're shared between Dottie, Kaylee and the 870; because Magpul Whore.  Behind the Aimpoint is the LaRue Po Boy LT649 with Hensholdt 2.5x magnifier.  For the longest I didn't have the optic far enough forward to use the magnifier, but today I was playing around and spotted that there's air between the delta-ring and the base of the M4s with it all the way forward!  The YHM rear has been replaced with a Knight's Armament 600m BUIS.


12MAY14

Replaced the Magpul MIAD with a Damage Ind. ECS grip.  I am more used to the angle thanks to the retro guns and it fits the M12 rack correctly.



16OCT14

Swapped the 14.5" barrel for an 11.5" from Sabrina.  Only 8 lb. as pictured, 6.9 lb. if you yank the Aimpoint and light.


Later, the same day, I decided that the Wilson Combat Accu-Tac was just plain cooler and it bothers Willard to no end to see a three-prong on an AR.  It's a very effective flash-hider, there's actually less visible flash from the three prong than with the 4.5" moderator that was on this barrel with Sabrina.



09MAR15

Put her back pretty much to where I had it six months ago.

It's become quite fashionable to bash things that are now obsolete as crap as if they'd always clearly been crap all along.

So crappy that they were obviously obsolete years before they were supplanted by newer designs.

The arguments are always expressed in a vacuum where many if not all of the influencing factors are flat ignored.

Reminds me a lot of book and film critics.  You know, the people that don't create a damn thing yet sit in judgement of the worth of the product when they are not, in fact, the customer?

Just because there is something better does not make it bad.

It's why some debates are so tiresome.

You read some sites and it's a wonder we won in WW2 with all the crap we had to work with.  Yet...

It's only the jaundiced modern eye looking back that sees the lack of worth and not the contemporary view.

Because we have neighbors who won't take their disease ridden pets to the veterinarian for preventative care (or at all), we end up having to make extra trips to the vet for our dog.

Every damn spring he catches some sort of itching disease from the mange looking dog next door.

The vet assures us that this would be completely eliminated if people would just get their dogs treated for the mites that carry the bacteria.  But they don't and we end up having to get our dog treated for the infection for mite mating/migration season.

Gods dammit!

There Is No Standard

Reading about New Jovian Thunderbolt's adventures in 1911 gunsmithing really brings something to the fore.

There is no such thing as AN 1911.

Every single manufacturer has their own thing going on.

Something he mentions several times is how Springfield Armory uses some sort of epoxy instead of a pin to retain the ejector.

I want to know when this change happened, because my Springfield Armory M1911 A1 USGI has the pin.


So does my Colt for that matter.


I collect military tech manuals.  The 1911 manual doesn't call out all of the meticulous fitting and measurements I've been reading about.  It's put in the part, does it work?  If not discard this obviously defective part!

TM 9-1925 (09NOV42):


13. General
     a.  Since all parts of the pistol are standardized as to their dimensions, repairs to a large degree consist of making the necessary replacement of worn, bent, or broken parts. In some cases, parts can be bent back or otherwise returned to their proper shape with satisfactory results. This applies to the leaves of the sear spring, the trigger, and the hammer strut. A worn sear notch in the hammer may be corrected by stoning or filing. Dents in the magazine usually may be removed and the lips returned to original shape by bending. Burs on muzzle of the pistol should be stoned off as outlined in paragraph 11 d (1).
14. Replacement Of Parts
     a.  Where parts or assemblies are broken or worn so as to render them unserviceable, they must be replaced from stock.  Often only parts of the assembly will be worn or broken and others can be salvaged.  However, should it take more time to remove serviceable parts than they are worth, the entire assembly should be scrapped.  In quantity overhauling of pistols, the parts of each should be kept separate for ease in determining to which pistol they belong.
15. Repairs
     a.  Burs on cams and on other smooth surfaces should be removed to make the part serviceable.  A very fine file is used, and care is taken to remove as small an amount of metal as possible.  Where roughened surfaces are present on moving parts, an oil stone should be used.
     b.  Correction of trigger pull.  Pistols received from the field usually have a trigger pull varying over a slightly wider range than new or repaired pistols (par. 3 a for trigger pull data).  Too heavy or too light pull may be corrected by stoning the mating surfaces of the sear and hammer until they meet squarely.  Do not stone off the notch in the hammer at an angle as this may decrease the safety of the pistol.  The trigger pull also may be varied up to approximately 1/2 pound by bending the leaf of the sear spring slightly.  The mainspring may require replacement if the pull remains too light after making these corrections.  All pistols should be tested for trigger pull, as outlined in paragraph 7, after making repairs, and before they are again placed in storage or service.

That's the entire repair section of the TM.  The rest is about how to tell if a part needs replaced and the procedure for swapping it.  There's obviously tribal knowledge imparted to the user of this manual that they get from armorer's school, but it's also clear that they expected parts to just drop in.

Doing It The Hard Way

I am willing to bet that the accepted gunsmith way of cutting the notch into the ejector isn't the way it was done when making military guns.

The gunsmith way is a bunch of careful measuring and duplicating the old notch in the new part and lots of installing the ejector and making sure the notch lines up with the hole.

Wanna bet that the original way of making that notch was to fixture the frame so that the hole was lined up with a drill bit or end mill, the ejector installed and then the drill was passed through the hole in the frame, cutting the notch for the pin?

Or that the hole in the frame for the pin was drilled with the ejector installed?

Why do I bet this?

Because it's a process that makes sense on a production line where every part is made to be identical and interchangeable.
