ATI Alpha Maxx RIA | 5.56x45mm | 16″ Pencil | ATIGAX5569ML60

The American Tactical / ATI Alpha Maxx RIA is a semi-automatic rifle offered in listings for 5.56x45mm caliber with a 16″ pencil profile barrel and a 9″ polymer M-LOK handguard. It is described in vendor materials as including flip-up sights and a Nano composite lower parts kit, presented in a black finish. A practical optic pairing under $1000 would be a Vortex Strike Eagle 1-6×24, which complements the rifle’s intended range and target roles without exceeding the recommended budget for a reliable mid-power optic.
