Among the unique new firearms at SHOT Show 2018 is a shotgun unlike any other. New from American Tactical, or ATI, is their American Tactical AR-15 Shotgun chambered for .410 bore.

American Tactical has been teasing this gun for a while and quietly launched it in 2017. It’s compatible with standard AR-15 parts and receivers and can easily be converted to 5.56 NATO, 300 AAC Blackout and more. Best of all the company is loading their own .410 ammo to ensure a constant supply of reliable, low-cost ammunition.

The shotgun is part of American Tactical’s Omni Hybrid series of ARs. These low-cost, lightweight guns have alloy-reinforced polymer receivers that push the AR design into new territories.

The American Tactical AR-15 Shotgun is a rifle-styled, smoothbore gun with an 18.5-inch barrel. The barrel is threaded for combination muzzle devices and chokes with additional chokes sold separately.

The shotgun comes with M4 A2-style furniture and a free-floating 13-inch KeyMod forend. The upper receiver and handguard sport a full-length flattop rail for accessories including red dots, lights and laser sights.
