Made from a 7075-T6 hard-coat anodized aluminum forging, the upper receiver is complete with brass deflector, forward assist, and full-length Picatinny rail. The lower receiver features a generous flare on the magazine well for easy magazine insertion.

Venting holes in the upper receiver, barrel extension, and bolt carrier ensure that excess gas is directed safely away from the user.

The Magpul MOE SL^® stock and MOE^® grip provide positive control and ergonomics. The receiver end plate includes an additional socket for a QD sling swivel pocket and fills the offset space at the rear of the receiver.

Compatible with mil-spec MSR trigger groups, receiver end plates, charging handles, pistol grips, and adjustable stocks.

4140 chrome-moly steel barrel is cold hammer-forged with ultra-precise 5R rifling. The heavy profile barrel balances nicely and its attractive, black nitride finish helps ensure exceptional accuracy, longevity, and easy cleaning.

15" aluminum handguard is free-floated for accuracy and features Magpul^® M-LOK^® accessory attachment slots along the 3:00, 6:00 and 9:00 positions and a full length Picatinny top rail. Sockets for Quick Detach sling swivels located at the muzzle end of the handguard allows for comfortable carry with a two-point sling.
