Introducing the latest high quality AK part manufactured by Arsenal, Inc. The AK-47 type Muzzle Brake for 7.62x39 caliber rifles carries the Arsenal Inc logo and the US marking as a testament to its uncompromising quality. The new brake combines a slick design with detailed attention to perfect functionality and workmanship. This brake is made in one piece and incorporates the ever-popular crescent design. The one-piece design creates a perfectly symmetric compensator, resulting in an equal amount of excess gas escape and uniform recoil reduction with no negative effect on accuracy. Made of Stainless Steel, this brake is resistant to corrosive ammunition and is designed for longevity and durability. 

The 3 ports on the top are positioned to counter the natural "high and to the right" recoil by forcing gas pressure out of the holes to counter muzzle rise. The half-moon cuts on each side force the gas flat out to the right and left which keeps the barrel steady shot after shot, and it's designed for a bayonet to mount without interfering with performance. All in all, an extremely effective muzzle brake that keeps you both on target and reduces felt recoil. An absolute must have for your AK!

Utilizing state of the art CNC machines, Arsenal Inc. ensured that the unit is coaxial, with the threads and the two concentric circular openings being centered and perpendicular to the cylindrical body of the compensator. The combination of high-grade tool steel and sophisticated heat-treating process in vacuum furnaces result in a compensator that maintains its perfectly cylindrical shape, free of any warping, deformation, collapse, or surface contaminants. 

The consistent and precision cut 24x1.5mm right-hand threads eliminate the wobbly effect common with other units. The compensator remains rock solid even if the incorrectly cut threads on your front sight block do not allow it to screw on flush with the wall of the block. 

The plunger pin notch is located at 12-o’clock position to match the timing with the standard AK-74 type front sight block
