The OR configuration delivers a flat-top A3 upper with a T-marked Picatinny rail (S&W marked near T12) and a pinned, low-profile railed gas block. No factory sights are installed, aligning with the Optics Ready setup.
The 16-inch M4-profile barrel is marked "5.56 NATO 1/9" and is threaded at the muzzle, capped with an A2 flash suppressor. A carbine-length gas system supports reliable cycling, and the 1:9 twist rate is a versatile pairing for common 5.56/.223 loadings.
The rifle uses a semi-automatic, direct impingement action and includes the forward assist, dust cover, and shell deflector. The receivers are forged with a matte black finish, and a manual safety is fitted. It accepts AR-15 pattern magazines, with an effective capacity up to 40+1 when using the included 40-round mag.
Furniture includes a 6-position collapsible buttstock with S&W logo, an A2-type polymer pistol grip, and a carbine-length two-piece polymer handguard. Length of pull is approximately 10.5 to 13.9 inches, allowing a broad fit range without adding bulk.
Made in the United States, this M&P15 OR is cataloged under S&W part number 150644 and arrives with four magazines and the factory hard case for secure storage and transport.
