ATI Alpha MX 7.5″ 5.56MM 60RD Binary | Rear Brace

The American Tactical / ATI Alpha MX 7.5-inch chambered in 5.56MM is a compact semi-automatic platform built with polymer upper and lower components and a short 7.5-inch barrel. It ships equipped with a 60-round windowed magazine, flip-up sights, a rear brace and a Franklin Binary trigger. For a sighting solution that complements the platform without exceeding typical budgeted optics, a Vortex SPARC AR red-dot (or an equivalent micro red-dot under $1,000) is a practical choice that maintains fast target acquisition and low weight.

Typical applications include range training and practical/competition shooting where compact handling and extended magazine capacity are priorities.

The Alpha MX is a compact, high-capacity 5.56 platform intended for shooters who prioritize short-barrel handling and extended on-target time. Its polymer construction reduces weight while the included 60-round magazine lowers reload frequency for extended range sessions and competition stages. The Franklin Binary trigger gives a distinct firing characteristic; prospective users should verify local regulations and suitability for intended uses before purchase.
