Bought most parts from Brownells... Using a few non-period specific items but it will be close
(Using fenced lower from Anderson and an enhanced trigger from PSA)
But... I am using proper upper, butt stock, barrel and handguard, teardrop forward assist, carry handle sights etc
Using you tube videos helped as I did the lower parts kit install (never did that before)
Now on to the upper, etc.
Should look and feel like the one I shot in 1976 in USAF
