15th Model CQB MBS

CQB Muzzle Break Suppressors

Designed for 11.5 inch Colt Commando, The 14 1/2" M4 and similar weapons

This model attaches to the weapon via a patented muzzle brake and an adapter that goes over the barrel for silencer alignment. When fired without the suppressor the muzzle brake effectively reduces recoil and muzzle climb while diverting muzzle gasses slightly forward, away from the shooter. The muzzle brake design eliminates upward and downward blast while reducing muzzle flash. The suppressor mounts via threads on the outside of the muzzle brake centering on a fitting that locks over the barrel. On the M4 this fitting stops forward of the M203 cutout allowing the mounting and use of the M203.
