"Colt has a proven track record producing M4 and AR-15 rifles for law enforcement use, and the Colt M5 Carbine Semi-Auto Rifle takes the mil-spec carbine to a new level with upgrades that improve upon the platform's performance and reliability. The M5 features the all-new modular M-LOK-compatible upper receiver and handguard assembly with improved barrel retention and interface. The new interface provides a true free-floated barrel along with enhanced rigidity and alignment. The redesigned lower receiver has integrated ambidextrous safety selector, mag release, and bolt catch/release so it accommodates both right- and left-handed shooters. The 16.5"" barrel is made from Colt's proprietary Cr-Mo-V steel and is chrome-lined for enhanced durability. The M5's 7-sided M-LOK handguard features a continuous Picatinny top rail and keyed anti-rotation tab. It comes complete with a Radian Raptor ambidextrous charging handle and TROY metal folding BattleSights, so it's ready right out of the box. Low-profile gas block with carbine-length gas system. Mil-spec HP/MPI-tested bolt and chrome-lined carrier with staked gas key. Includes one 30-round magazine.
