The MCX-SPEAR’s hybrid .277 SIG FURY ammunition utilizes a two-piece case with a steel base, allowing for higher chamber pressures (80,000 psi) and a flatter trajectory than 7.62 NATO. The short-stroke piston system isolates heat and carbon from the action, a critical feature for sustained fire. This design is the result of SIG SAUER’s Next Generation Squad Weapon program, engineered for definitive terminal ballistics.
