Single expansion chamber with 36 total ports, 18 on each side, angled 8° forward, provides increased recoil control. Gas and sound are moved forward, away from the shooter. Non-vented top and bottom surfaces reduce muzzle rise while limiting dust signature. CNC machined for precise fit with very little finish work required. Rear of comp can be tapered to conform to barrel. Made in the USA.
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.
