I am looking for a flat top M4 upper with standard front sight tower. Barrel must be threaded, and can be 14.5-16" long. Will consider 14.5" barrels w/ permanantly attached FH. Don't need B/C/CH or carry handle. Will consider uppers with flip-up sights. Thanks!
Will buy outright, or I have the following guns to trade for the M4 upper:
-Glock 27 .40 cal
-Ruger Blackhawk .357
-Ruger Single Six .22LR/Mag
-Ruger Super Redhawk .44 w/ 2x Leupold
-Ruger Mark II .22LR 4" w/ fixed sights
-Rock River 16" SS bull barrel upper 1/8
