Upper has less than 200 rounds through it of quality black hills ammo, mostly shot with my SDN6 but also with my M4-2000. Accuracy was within an inch at 100y, not surprising with BCM’s barrel.
I built this upper to look like a true MK12 Mod 0 but with the shorter barrel to use with my AAC suppressors, and still have the classic look.
I am asking $1,400 shipped CONUS.
Paypal gift or USPS Money Order.
Not looking for trades and won’t split anything up.
If it wasn’t listed above it isn’t part of the deal and isn’t for sale.
Thanks!
