This is a Colt/Harvey SP1 large hole upper with bushing with a 20" pencil barrel marked C MP C
and an A1 birdcage flash hider.
It also comes with a complete M16A1 trap door buttstock assembly and a M16A1 pistol grip.
This is a great little light weight package that shoots very accurately.
I will trade everything pictured for a complete A3 chrome lined barrel upper with carry handle or BUIS with a 1-9 or 1-7 twist 14.5" or 16" barrel.
Armalite, Bushmaster, Colt, Stag or RRA only!(complete upper, complete buttstock assembly and pistol grip)
SOLD Pending Funds to DrjonesUSA
