I have an excellent like new condition complete 16" carbine upper for sale, built basically as a Colt 6721 clone upper. Was built with proper tools using all new parts. Has been zeroed / test fired 120rds WWB ammo. The FSB is not canted and as I zeroed it, I have only 3-4 clicks of right windage for L to R zero. It's a very nice upper, I just want to get into some other stuff. Don't really have the need for a 4th AR when my other 3 get very little time at the range as of late.
-Colt 6721 barrel assembly

-Aero flat top upper with anodized M4 ramps
-Charging handle (RRA?)
-CAR handguards 6-hole RRA
