This is the '4 Gill' design - a very distinctive longer profile with 4 angled-back gills on each side together with 2 'nostrils' at 10 and 2 o'clock. As well as the individual design, it has a unique construction - it's made of stainless steel that then receives a black nitrate coating.
Screws onto standard M14 x 1 threaded barrels (with 5.56 / .223 bore)
Muzzle brake has four chambers with 10 ports that direct the exiting propellant gasses upwards and to both sides to reduce muzzle climb and felt recoil - allowing for faster follow-up shots
There are no open ports on the bottom of the muzzle brake core - this will reduce the dust signature when firing prone
CNC machined stainless steel construction with smooth black Nitride coating
Crush washer AND Jam Nut included to aid fitment
Dimensions: 3.34" x 0.97" x 0.89"
Weight: 5.1 oz. (145g)
Model: CMMB314SSBKMB
We recommend a screwdriver with a few wraps of duct tape around the shaft - insert through the 'gills' of the brake and then twist on to crush the washer and keep it all straight and tight. Just ensure that you don't turn too far - if you back off you will need a new crush washer!
