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 1/2" x 28 threaded barrels
This brake has been specifically manufactured for 9mm - perfect for your Just Right Carbine (JRC)!
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"

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!
