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.

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.

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.

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.
13FEB12A little more genuine! Got the tax stamp and added a 14.5" pencil barrel. The Trilux is a bonus addition.
04JUL12I 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.
06MAR13Ditched 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!
31DEC13Although 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.
