EXTREMELY RARE! Complete conversion unit that replaces the slide/barrel of YOUR steel 1911A1 45 auto with a single shot 223 Remington 14.9 inch barrel. Besides being fun to shoot, this conversion unit would be a nice addition to your backpack! This is new, never fired. It installs easily and comes with the manual and the barrel release mechanism which inserts like a factory 1911A1 magazine. It has a fully adjustable rear sight. Also included is a Weaver scope rail made for this unit. Private seller. Daylight only. Meet at my choice of a safe location close to Cactus and I-17. Cash only!
