Just finished this build. It's a clone of my boot camp rifle. US Army, A co 2/54 Infantry on Sandhill, Ft. Benning, GA 1993. SFC Hinkle was my lead Drill Sergeant
DPMS stripped A2 upper (got it from CDNN for $39)
Windham Weaponry A2 front end, 1/7 barrel, upper parts kit
BCM lower purchased during Sandy Hook panic
Rock River A2 stock kit w/ USGI cleaning kit inside
Geisselle SSA trigger (OK, didn't have this in boot camp)
BCM bolt carrier group
USGI M1 sling (didn't have this in boot either, but I'm an Appleseed instructor, so it's a must for me and my accuracy standards)
USGI pistol grip and charging handle
It's a shooter! 50m 5 round zero target with XM193! Shot from prone unsupported with loop sling per Appleseed standard. Zeroed using Molon's Revised Improved Battlesight Zero. Haven't stretched it further than 50m yet, but will soon.
