Muzzle Brakes

Do-It-Yourself vs. Custom Installed 

• Do-It-Yourself are for primarily for pre-threaded AR-15 and LR/SR308 barrels. They usually come in .22 caliber bore with 1/2x28 threads. OR, .30 caliber bore with 5/8x24 threads. We also have some are for special purpose pre-threaded barrels (like 350 Legend, etc.)
• Custom Installed Brakes are threaded to fit the contour and bored to fit the caliber.
