16" Colt 1:7 lw barrel on CMT flat top upper receiver w tmarks
Barrel marked C MP 5.56 NATO 1/7-chrome lined
Factory M4 feedramps
Threaded muzzle with A2 FH

321 rds. through assembly
The BUIS looks to be a chopped carry handle. The upper looks like new and fits very nice onto my mega lower in the pics.
This is a very lightweight upper compared to my 14.5" M4 upper. I never knew there was such a huge difference.
THIS IS FOR THE UPPER ONLY! No b,bc,ch, or lower. For the upper and buis.
