The Precision Armament EFAB 7.62 hybrid brake (brand part no. A04488) is the .308 and 7.62mm version of the company’s enhanced flash-arresting brake, cut for 5/8×24 threads. Its diverging expansion nozzles diffuse and cool the gases for strong recoil reduction and low flash, with less concussion to the sides and rear of the shooter. The body is machined from heat-treated 416 stainless steel with an Ionbond CrCN coating, and the closed bottom reduces dust when shooting prone. A shooter who found a traditional .308 brake too loud for the people nearby will find this one calmer.

Frequently Asked Questions

Which caliber should I choose? Precision Armament says to choose by the actual bullet diameter of your cartridge. A .300 Win Mag, for example, takes a 7.62/.308 device because its bullet is .308 inch.

What alignment accessory helps? Precision Armament recommends its AccuWasher muzzle device alignment system for best performance. It is not included.

Can I use a crush washer? No. Precision Armament cautions not to use crush washers with this product.
