Muzzle Brake 5.56 Caliber with 1/2-28 Threads for the AR Platform
About MB-15 (1/2-28 Threads)
Our muzzle brakes are a great looking and very effective muzzle device for rifles, AR pistols, and featureless rifles in restricted states. The larger side ports mitigate recoil, and the 4 small top ports direct blast up to mitigate muzzle rise. They are available in 1-port, 2-port, and 3-port sizes, and are chambered in 5.56 (.223) with 1/2-28 threads. The 3-port size is the perfect length to bring a 13.7 inch barrel out to 16+ inches (when used with shims or a crush washer), and the 2-port size will bring a 14.5" barrel out to 16+ inches. These brakes can help you meet minimum length regulations when permanently attached (pin and welded or high temp silver solder), and the bottom is blind drilled for a pin if needed. Precision Machined from a hardened 416 stainless steel which is highly corrosion resistant and very strong. There are two color options, matte black and raw stainless steel. NEW AND IMPROVED AS OF 1/17/23 the matte black is
sandblasted and then high temp Cerakote® in jet black is applied steel shot blasted and then black nitrided. The black muzzle brakes include a black (parkerized) milspec crush washer, and the stainless muzzle brakes include a stainless steel crush washer. Black and stainless steel crush washers are also available separately for purchase. Proudly made in America!

Note About Colors and Finish
We try our best to accurately represent all colors on our website photos.
The high temp Cerakote® color is Jet Black V-169 and is capable of temperatures up to 1800°F. V Series coatings provide unmatched high temperature performance, while providing excellent chemical resistance, durability and aesthetics compared to the typical firearms Cerakote® colors. On the raw stainless muzzle brakes, there may be some very small dents or imperfections in the machined surface. This is the nature of CNC lathe turning when tiny metal chips get into the sub spindle collet and then are pressed into the part surface when the collet closes. This is rare, but does happen and can appear on the raw stainless parts because they are not sandblasted or coated. See sample image below (keep in mind that this is a closeup photo with high contract lighting so the small blemish can be seen)...
