I have a box of AR15 odds and ends, 9 rifle gas tubes, barrel nut, delta spring and delta C spring.
Also a Colt A2 upper with forward assist and port door cover, upper was from South American M16 with finish worn off and was spray painted, works fine and could be refinished with alumahide or similar for a decent upper or for experimentation.
Knights Armament forward grip that is painted tan.
Mystery remote switch for light or? Has velcro pad on back of switch and plug on other end.
