Manticore Arms Nightbrake Features The Manticore Arms Nightbrake is machined from 8620 steel and threaded 5/8x24 making it a direct fit for any AR-10 or other rifle with a matching threaded barrel. Eighteen ports are distributed around the upper 270 degrees of the device directing propellant gas upward and to the sides to help counter muzzle rise during rapid fire. This port layout reduces exiting gas pressure in a way that helps keep the rifle s point of aim steadier between shots. The compensator is rated to clear any projectile up to .30 caliber giving it broad compatibility across common AR-10 and SR-25 chamberings. Installation is handled through the device s integral wrench flats allowing the Nightbrake to be properly torqued onto the barrel using a standard wrench rather than a specialty tool. An included crush washer ensures correct timing and a secure fit once the compensator is tightened down. At 1.875 inches in overall length the Nightbrake adds minimal length to the barrel while delivering its recoil and muzzle control benefits. Manufactured in the USA the Manticore Arms Nightbrake is a dependable muzzle device upgrade for sale at GrabAGun.
