The MCX-SPEAR LT’s piston-driven operating system is a key technical advantage, diverting gas and carbon away from the action. This results in enhanced reliability with varied 5.56/.223 ammunition and less frequent cleaning. The 1:7 barrel twist optimally stabilizes both lighter 55-grain and heavier 77-grain projectiles, making this rifle a versatile platform for duty, defense, or extended training sessions.
