Got my engraved 80% lower back today! Now it's back on me to finish the fire-control pocket.
Then it will be on someone else for anodizing. Then it'll be part of an M16A2 clone.
Got the M16 type D stock I won on GunBroker today too. It's in unissued condition and the seller included a nicely mottled A1 pistol grip too.
Aside: I hate the term "A1 pistol grip" because that grip is used on all the black furniture guns until the M16A2 style comes around.
