Keymo Muzzle Brake

by Joe, Verified Owner from TX, United States Written on January 20, 2026
I’ve bought several of these breaks for my 30 calibers. Never had any issues using them. Great price and easy to install on your own. Will purchase again in the future if needed. I recommend this muzzle brake for your suppressor set up.

Keymo Brake

by JS, Verified Owner from TX, United States Written on March 15, 2025
Brake worked as intended with not issues on lockup or alignment. Make sure you grease the lugs and work it a few times before firing as recommended, or it will not come off that easy when removing a suppressor. Brake can take a while to time but is supplied with multiple shims. I torqued more than suggested because it came loose when taking the can off while still warm. Loctite can be used if preferred
Pros:
  • Pricing against other options
Cons:
  • None
Best Used for:
  • keymo adapter to swap cans
Would recommend: Yes
