CMMG Releases Mk4 3GR “3-Gun Rifle”

    Not content with only 12 rifles in their Mk4 product line, CMMG has announced the release of the 3GR “3-Gun Rifle.” It comes standard with a 18″ stainless steel barrel, CMMG’s excellent RKM14 keymod handguard. and a Geissele SSA trigger.

    TTAG has had a moment with the rifle. It seems that the Muzzle Break is a bit too compensating… We will reach out to CMMG for our own evaluation.
