Sig Sauer Elite Match Grade 300 BLK 220gr OTM Subsonic 20rd

Sig Sauer Elite Match Grade 300 BLK is a subsonic load built around a 220gr Sierra MatchKing open tip match bullet. At about 1000 fps it stays under the speed of sound, which is the whole point of 300 BLK on a suppressed rifle: no supersonic crack, just the action cycling and the hit.

Sig loads these rounds with electromechanical monitoring for consistent dimensions, and the heavy MatchKing gives tight groups with minimal dispersion when shot through a can. It is a target and training load for suppressed AR rifles, and 300 BLK runs on standard 5.56 NATO bolts and magazines. Confirm your gun cycles subsonic ammunition before relying on it. Each box holds 20rd.
