Colt M4 Carbine Trooper 5.56 Nato 16.1 in 30 Rounds Matte

The Colt M4 Carbine Trooper Patrol Rifle brings the classic Colt AR-15 lineage into a duty-grade Modern Sporting Rifle that excels for patrol, range, and build-up projects, featuring a 16.1-inch 4150 CMV barrel with 1:7RH 6-groove chrome lining for reliable stabilization of 5.56x45mm NATO rounds and a manganese phosphate finish for corrosion resistance, while the 7075-T6 aluminum upper and lower receivers with black hardcoat anodizing deliver a robust, lightweight platform. The flat top upper receiver and M-LOK capable, lightweight extended-length Centurion handguard make it straightforward to mount optics, lights, and other mission equipment for tactical work or competition, the direct gas impingement carbine system and single-stage trigger give a familiar AR feel and controllable follow-up shots, and the reversible safety selector and six-position collapsible stock with Government A2 grip accommodate different shooters and duty rigs. Marketed under Colt's Trooper series, this semi-automatic AR-type rifle is an adaptable MSR for law enforcement training, personal defense setups, and advanced custom builds, and it requires FFL transfer for purchase and complies with common industry specifications sought in searches for Colt M4, Trooper M4, 5.56 NATO carbine, chrome-lined barrel, and M-LOK AR platforms.
