Features an innovative reverse venting triple baffle design for the highest recoil reduction in its class. The M4-72 is an extremely lightweight (2.6 oz) and compact design that delivers industry leading recoil reduction of up to 75%. Closed bottom construction combined with upward biased venting effectively eliminates both muzzle rise and dust signature. Precision machined from heat treated stainless steel for superior durability, the M4-72 can withstand the extreme heat of combat conditions without being subject to rapid erosion. Available with an advanced Ionbond® high temperature CrCN coating (matte black), or stainless steel in-the-white (satin grey). Accu-Washer™ Muzzle Alignment System required for installation.

.308/7.62mm model is designed to fit any caliber from .243 Winchester up to and including 338 Lapua Magnum (6.5 Creedmoor, 308Win, 300WM, 30-06, 338LM, etc.) and features 5/8-24 threads. Delivers industry leading recoil reduction of 65-75% depending on the cartridge.

Additional Information:

I don’t see my caliber listed, which one do I select?

When selecting a caliber for one of our muzzle devices, the correct choice is based on your cartridge’s actual bullet diameter. For example; if you have a .300 Win Mag, you would select a 7.62/.308 muzzle device. This is because the bullet for that cartridge is a .308″ diameter.

Can I put this on my shorter-than-14.5″ barrel?

You can, we just don’t really recommend it. Reverse-venting brakes do just that; vent gases in the reverse direction from where they were traveling. This design is how such high recoil reduction ratings are achieved. But because of that, gases and concussion are directed back to the shooter. Barrels below 14.5″ can cause these forces to be quite drastic to some individuals, and more extreme depending on what caliber you are shooting.
