What’s Included
- One 30-round Magpul PMAG polymer magazine
Forged 7075-T6 upper and lower receivers give the rifle a solid, mil-spec foundation. The upper is T-marked along the flat-top Picatinny rail to simplify repeatable optic placement, and it includes a forward assist and ejection-port dust cover.
The 16-inch light-profile barrel is cut from 4140 steel and finished inside and out with Armornite for corrosion resistance. It is threaded 1/2-28 and fitted with an A2-style flash hider. A carbine-length gas system keeps recoil manageable while maintaining reliability.
Sights consist of an A2 F-height front sight post pinned to the gas block and a Magpul MBUS flip-up rear, providing a ready-to-use iron sight setup. The handguard is a ribbed, two-piece polymer unit that stays cool under sustained fire.
The six-position telescoping stock lets the shooter tailor length of pull from 10.25 inches onward, and the A2-pattern pistol grip offers a familiar hold. Standard controls include a right-side magazine release and an ambidextrous-compatible safety selector.
