The ATI Alpha Maxx (brand part no. ATIGAXP4109ML) is a .410 Bore shotgun pistol built by American Tactical for shooters who want a compact, magazine-fed smoothbore for home defense or close-range utility work. Listed here in the over/under lineup, this is actually a repeating-action pistol rather than a break-action double gun, with a stockless pistol format and a modern accessory rail up front. Its short overall length and quick handling make it a purpose-built option for truck guns and close-quarters defense rather than field shooting.

Key Specifications

• Chambered in .410 Bore for compact, controllable smoothbore rounds.
• Feeds from a repeating action with a 5+1 capacity, unlike a break-action double gun.
• The 8.75-inch barrel keeps overall length short for close-quarters handling.
• A 9-inch M-LOK rail up front accepts lights, lasers, and foregrips.
• A flip-up front sight folds down out of the way when not needed.
• The matching flip-up rear sight gives a fast, co-witnessed backup sight picture.
• A 1-in-20 rifling twist rate is built into the bore for stabilizing rifled slug loads.
• A black barrel finish resists wear and corrosion.
• Overall length of about 24 inches keeps the package genuinely pistol-sized.
• Ships at approximately 5 pounds unloaded.
