Post-ban compliant, BATFE has classified the Carlson Comp as a compensator and not a flash hider. This is the original Carlson Comp. This device allows the gas to be directed upward through the gas ports and the solid bottom keeps the muzzle down during semi and full auto fire. This device has proven very effective for fast follow up shots. The Carlson Comp has been tested and used by SWAT teams with great results.
