Have an excellent Colt A3 20" GI profile 1/7 chrome lined barrel assembly. Barrel has exactly 500 rds thru it, no lug. Comes with everything forward of the upper receiver, hand guards, gas tube, tube pin, delta assembly, A1 or A2 flash hider your choice and taller A3 front sight tower. Threads do have a dimple from a KKK comp I removed can't see the dimple if you screw a flash hider on, other then that its excellent.
