Description
Formerly known as the M4 Collar. The 7×7 Collar was renamed to avoid confusion with the M4 suppressors which they are not compatible. The name “7×7″ comes from the step the collar sits on. The step is roughly .700″ past the shoulder and the diameter of the barrel between the shoulder and the step is also around .700″. This is a very common step among a variety of barrels.
Designed to fit barrels with a .745″ barrel diameter after the 7×7 step.
Available in both A-Mount and B-Mount configurations.
