Notes
The SIG50 represents SIG Sauer's first production .50 BMG rifle, leveraging the company's extensive military contract experience with the M17/M18 pistol program and the MCX/MPX weapon families. The rifle features SIG's anti-glare finish and a 5-round detachable metal box magazine. The barrel's 1:15-inch twist rate is optimized for heavy .50 BMG match projectiles. The stock detaches for ease of transport, and the rifle ships with a hard carrying case and Harris-style bipod.
