- Caliber-Gauge:
- 410 Gauge
The ATI Alpha Maxx SGA is a compact, modern 410-gauge shotgun built for shooters who want a stripped-down, versatile platform that doesn't sacrifice real functionality. With an 8.75-inch barrel and a 5-round magazine capacity, this 410 delivers the firepower of a larger gauge in a package that's easier to handle in tight spaces—whether you're working around a truck bed, navigating brush, or just looking for a nimble shotgun that doesn't eat up closet space. The M-LOK handguard lets you mount lights, slings, or other gear without buying a whole new setup, and the rifle sights keep you on target out of the box.
This isn't a shotgun built for show. The rifled barrel and 1:20 twist are engineered to stabilize 410 slugs and shot columns, giving you genuine accuracy potential at distance instead of just a spray-and-pray gun. If you reload or handload 410 ammo, you'll appreciate the precision engineering here. The polymer furniture keeps weight down and maintenance simple—no wood to worry about in wet conditions or during long days afield.
The Alpha Maxx SGA fits hunters and sport shooters who've learned that smaller doesn't mean underpowered, and compact doesn't mean compromised. It's the kind of shotgun that rewards accurate shooting over raw output, and its modular design means you can evolve it as your needs change. Whether you're running it stock or building it into a dedicated platform, the ATI Alpha Maxx SGA is built to work.

Frequently Asked Questions
What is the rifled barrel and 1:20 twist good for?
The rifled barrel and 1:20 twist stabilize 410 slugs and shot, delivering greater accuracy at distance than smoothbore shotguns. This is particularly useful if you hunt or shoot slugs where precision matters.
Can I add optics or lights to the M-LOK handguard?
Yes. The M-LOK handguard is designed to accept standard M-LOK-compatible mounts for lights, lasers, optics adapters, and other accessories.
Is this 410-gauge shotgun suitable for hunting?
The 410 is a legitimate hunting gauge for smaller game and birds when shot placement and ammunition selection are respected. The 5-round capacity and accurate rifled barrel make this platform suitable for hunters who know their ballistics and distances.
What sights come with this shotgun?
The ATI Alpha Maxx SGA includes rifle sights mounted and ready to use out of the box, enabling immediate target acquisition without requiring additional sight purchases.
