Threaded ak-47 muzzle brake Fits onto most threaded ak-47 barrels Muzzle brake to reduce recoil Steel construction The AK muzzle brake - threaded screws onto the end of AK/arms with the 1 x 14mm left hand threads. The ports of the muzzle brake redirect the propellant gasses upwards and to the sides, reducing the felt recoil. It is made of steel construction with a length: 2.9 inch.
installed it to my converted saiga 7.62. Went to the range and shot about 300 rounds. never had a hitch. Made a difference in recoil felt compared to no muzzle brake installed. highly recommend it for the price.
