The M2-G1 is built to run cleaner and stay reliable when it counts. By collecting gas closer to the chamber and mounting the recoil system in the stock, it delivers smoother control and longer sustained performance than forward-mounted designs. The result is when it's time to call the M2-G1 into action, it will hold its ground and stay in the fight.
