Up for trade is my Colt M4 upper with 16" 1/7 barrel. No bayo lug, T-marks or B/BC/CH.
Upper has double heat shield handguards, M4 feed ramp extension, "F" marked front sight base.
I started off on something I can no longer finish, so I'll have to trade out if I want to complete my rifle. I'm looking for a RRA/Bushy/Stag upper + cash. Or maybe just cash. Let me know what you have and what your offer is. EMAIL through AR15.com hasn't been reaching me so please use IMs. thanks.
