Description

SIG 300BLK subsonic rounds are propellant chemistry optimized to produce the ideal amount of down-bore pressure for cycling both piston and gas driven platforms, with or without sound suppression. Engineered with the SIG MCX™ mission configurable rifle in mind – these rounds minimize recoil, sound, and muzzle flash while maximizing the number of shots on target.

SIG SAUER subsonic rounds feature a 220gr Sierra Match King Projectile for superior accuracy and minimal dispersion when suppressed.
