Reviews & Ratings for Kexuan Shark Muzzle Brake for .450 Bushmaster, 11/16x24 — 1 review — Page 1

I haven’t shot the gun yet that this is installed on so I can’t say how effective it is. The photo shows the muzzle brake, crush washer, and a lock washer. Mine didn’t come with a lock washer, only a crush washer. I have indexing washers for this size so I used those to set it up correctly on the muzzle. It’s on a .458 SOCOM 10.5” barrel. It’s relatively large but it looks like it will work to reduce muzzle rise. There’s ports on one of the flat horizontal surface and none on the other one so it’s easy to know which side is up. It’s well made and has a nice finish on it. It’s machined nicely and it’s very affordable.
