The MCX-SPEAR LT’s short-stroke piston system reduces heat and fouling in the receiver compared to direct impingement, enhancing reliability. The 5.56x45mm NATO chambering from an 11.5″ barrel balances ballistic performance with a compact profile, ideal for close-quarters use. The integrated IR laser is zeroed at the factory, providing an immediate capability for use with night vision devices without aftermarket installation.
