CMMG Resolute Mk4 DISSENT 300 Blackout 14.5" Upper Group

CMMG Resolute Mk4 DISSENT Upper Features The CMMG Resolute Mk4 DISSENT Upper Group centers on a 14.5 steel barrel with a 1:7 twist rate a rate matched to stabilize the heavier bullet weights common in .300 AAC Blackout loads for both subsonic and supersonic shooting. The pinned and welded SVD brake extends the barrel to a compliant overall length while still managing recoil and muzzle rise which keeps the upper legal to transfer without an NFA barrel-length concern. A non-adjustable .750 gas block delivers consistent low-maintenance gas system operation without a tunable port to fuss over. Together the barrel twist rate and pinned muzzle device make this a straightforward ready-to-run upper for a .300 Blackout build. The CMMG EML 13.5 M-LOK handguard provides a slim free-float platform with mounting slots at multiple clock positions for lights grips and other accessories a shooter wants forward of the receiver. Shipping as a partial upper group it arrives without a bolt carrier group or charging handle so an existing BCG and charging handle can be dropped straight in. The matte black finish on the barrel keeps the upper visually consistent with most black rifle builds and resists handling wear. Builders assembling a dedicated .300 Blackout upper for an existing compatible lower will find this a direct no-fuss way to add that caliber to their lineup.
