Krinkovスタイル .223 1/2x28 マズルブレーキ（前方反動低減）

Installed this on my AR pistol and the difference in perceived recoil is night and day, especially indoors. The included crush washer made timing it perfectly simple.

The threads on this thing are cut clean, and the included crush washer made timing it a breeze on my 16-inch build. It definitely pushes the blast forward and keeps the noise off my shooting buddies’ ears, which is exactly what I wanted.

Wasn't sure about the concussion reduction claim, but after a mag through my AR, the blast definitely feels pushed forward instead of slapping my face. The threads were clean and the crush washer seated it tight with no timing hassle. For the price, it's a solid upgrade over the bare muzzle.
