The Auto Ordnance Thompson SBR in .45 ACP is a semi-automatic short-barrel rifle that brings classic Tommy Gun appeal into a modern, compact platform. Built on the legendary Thompson design, this 10.5-inch-barreled rifle delivers the raw power and character of .45 ACP in a package that's nimble enough for home defense, range days, or tactical training without sacrificing the heft and reliability that built the Thompson's reputation. If you want a semi-auto rifle with genuine personality and stopping power in a short, maneuverable form factor, this is it.
The 10.5-inch barrel keeps the overall length to 35 inches, making this SBR easier to handle in tight spaces than full-sized rifles while maintaining the .45 ACP's substantial ballistic character. The detachable stock and vertical grip give you ergonomic control and the ability to configure the rifle to your preference—whether that's for administrative work, training, or transport. A 30-round magazine capacity gives you serious firepower downrange. The black finish pairs with classic walnut furniture, preserving that Thompson DNA while you work in a modern semi-auto context.
Sighting options include a blade front sight paired with adjustable rear sights, so you're not locked into optics if you prefer iron sights or want to run irons as a backup. At 12 pounds, it's substantial enough to manage recoil and run smooth but light enough for extended use without fatigue. This is a rifle that rewards shooters who appreciate the Thompson legacy and want a genuinely effective, compact .45 ACP platform without mall-ninja pretense.
