UA CMR-30 Muzzle Brake Barrel Shroud

  • Sale
  • Regular price $69.99

The Underworld Arms CMR-30 Muzzle Brake Barrel Shroud is the perfect addition to your CMR-30 chambered in .22wm. The six port design reduces muzzle flip and felt recoil and gets you back on target fast for shorter split times and improved battlefield effectiveness. 

The anodized matte black finish protects the CNC machined 7075 T6 muzzle brake from wear and reduces the visual footprint.  

Unlike other CMR-30 mock suppressors that only change the way your rifle looks, our mock suppressor is a fully functional muzzle brake that combines form and function. 

When mounting be sure the two mock ports are pointed down in line with the pistol grip and trigger with the six real thru ports pointed at 3 o'clock, 9 o'clock, and 12 o'clock. Blue locktight is what we suggest for timing your muzzle brake, apply blue locktight to barrel threads, position muzzle brake as indicated above, and let cure for 24 hours before using your rifle.
