The Auto-Ordnance Thompson 1927A-1 Carbine with a detachable walnut buttstock (Auto-Ordnance part no. T1B50D) puts a genuine twist on the classic Thompson platform in .45 ACP. Built by Auto-Ordnance, this carbine swaps the fixed stock found on other Thompson models for a detachable walnut buttstock and vertical foregrip, letting owners break the carbine down for storage or transport. A 16.5-inch finned and threaded barrel wears a factory compensator to tame muzzle rise, and the carbine ships ready to run both a 20-round stick magazine and a 50-round drum magazine straight out of the box. For collectors, range enthusiasts, or anyone who wants the Thompson experience in a more compact travel package, this carbine delivers.
