Key Features and Tactical Benefits

Ambidextrous Controls

Ambidextrous ergonomics are a highlight: the charging handle, safety selector, and magazine release are all mirrored for left- and right-handed shooters. These controls improve speed and adaptability during drills and defensive actions, and simplify training for mixed-hand stances.

Optics and Muzzle Device

The bundled Vortex Crossfire II 1-4X24MM scope is a low-power variable optic ideal for fast target acquisition at 1x and precise follow-up shots at 4x. The included muzzle brake helps tame recoil and muzzle rise, allowing quicker sight re-acquisition and tighter groupings during rapid strings of fire.

Magazine Capacity and Readiness

Two 30-round magazines ship with the rifle for immediate use at the range or for training. Magazines are a practical baseline for drills; users can supplement with additional magazines to suit their training routine.
