The Hammer muzzle brake is new to the line up!!  The slots are angled up 30 degrees for the maximum stoppage of muzzle rise. No need for a crush washer with our over the barrel design lock nut! The center of the brake is machined out to safe weight. It does not make the gun more quite, but it does change the tone.  These are avalible in 5/8-24 thread, 6.5 and .308 caliber, flat black, and FDE in stock now!  The Hammer and lock nut are sold together for $129.00 plus shipping.
