Description Our first signature brake we named the “SHARK” due to its appearance of shark gills. 1.75″ diameter, threaded 1-14 bored .54 for the 50 BMG. This design creates no dust imprinting. We suggest installation by a competent gunsmith. Timing, concentricity to bore and brake bore clearance must all be finished. Brakes are supplied with a .245 bore. Please review table in the next tab Thru Bore Table. This style of muzzle brake is being discontinued. After in stock inventory has been sold out, we will not be making any more.
