This steel muzzle brake features a slim design and 42 porting holes drilled at a 7 deg forward angle.
Once the brake is connected it counters recoil and unwanted rising of the barrel. The porting holes provide openings for gases to be expelled to improve follow up shot accuracy.
*Note - Gunsmithing required. Comes with a .220" (nominal) diameter exit hole that must be opened up to .020" larger than bullet diameter.
For calibers over .308 you will have to open up the inside diameter completely through the muzzle brake. Ensure there is a minimum of 0.125" wall thickness per side after opening to the proper diameter.
