All major components are produced in-house making for dependable quality control. The M&P15 features an 16" free-float modular rail forend, a military-spec flash suppressor compensator, a six-position telescopic butt-stock with dual sling attachments, and a bolt catch and two-position receiver-mounted safety lever that work together to eliminate dangerous mishaps. The OR model has a chrome-lined bore, gas key, bolt carrier, and chamber for durability. The barrel has 6R rifling and a 1 in 9" twist. This rifle features a pinned stock and a 10-round magazine and comes with the original factory box. Its stock, metal, and bore are all in very good condition.
