Multi-port brake softens recoil and reduces muzzle rise. A single expansion chamber and 42 total ports angled 8° forward provides increased recoil control. Gases and sound are directed forward, away from the shooter. Features crenulated end. Made in the USA.
Works as is with .30 caliber rifles. If shooting higher caliber, gunsmithing is required. Exit hole must be opened up to .020" larger than the bullet diameter. For calibers over .308 you will have to open up the inside diameter completely through the muzzle brake. Ensure there is a minimum of 0.125" wall thickness per side after opening to the proper diameter.
