The X Series muzzle brake and suppressor adapter remains installed on your firearm and allows direct threading of several suppressors! Its lighter, Shorter, Simpler and Less expensive than most QD systems on the market while maintaining all the positive attributes of a direct thread mount! There are no adapters involved the suppressor threads DIRECTLY onto the mount! The other great thing about the X-Series brake mounts it that they add 2 additional blast baffles to protect your suppressor!

This muzzle device is perfect if you’re trying to build a small and lightweight package. I installed it on my 6.75” MCX and it honestly feels like a new gun. Top notch quality and design as per usual. Can’t recommend enough
