One of the most commonly used brakes is the Russian Ak 74.
When I built my Saiga 74, I put one on just to complete the look. I went with a real Bulgarian "zig-zag" 74 brake, not the cheap Tapco version, which is said to be worthless
However, even though the 5.45 has little recoil to begin with, I have been amazed at how effective this brake is.
When I shoot the rifle even moderately quickly, I can feel the muzzle being held down...and the recoil is nonexistent.
