Auto-Ordnance Thompson 1927A-1 SBR | .45 ACP | 10.5in

The Auto-Ordnance Thompson 1927A-1 short-barrel rifle is a semi-automatic, NFA-designated carbine-pattern firearm chambered in .45 ACP with a 10.5 inch barrel and a walnut vertical foregrip. Its configuration follows the classic Thompson styling while using a modern semi-auto action suitable for range use and historical collection displays. For an optic that pairs well without exceeding a $1,000 budget, consider a compact red-dot such as the Vortex SPARC AR for fast target acquisition and robust durability.

Applications: recreational range shooting and historical/collector display.
