The Ultimate Hybrid Muzzle Device EFAB (Enhanced Flash Arresting Brake)

Combines superior muzzle control with effective flash suppression even on barrels as short as 10 inches. Patent Pending EFAB technology uses an innovative configuration of diverging expansion nozzles to both diffuse and cool combustion gases resulting in maximum recoil reduction with minimum concussion to the rear and sides of the shooter. Closed bottom reduces dust signature when shooting prone. Precision machined from heat treated stainless steel with an advanced Ionbond high temperature CrCN coating for extreme durability. Features pilot hole for permanent pinning to bring 14.5 barrels to legal length.

This compensator is designed to fit .223 caliber (5.56mm) AR-15/M16/M4 style rifles with 1/2-28 muzzle threads.

Accu-Washer Muzzle Alignment System required for installation (not included).

Finally, a muzzle device that is worth $160Review by DeputyBravo
I have been using my EFAB for almost 1000 rounds now and it delivers everything it promises. It shoots FLAT and neutral. No muzzle dip like some other devices that are in the same price range. It also doesn't increase gas system pressure (a plus), which causes the bolt carrier and buffer stack to bottom harder in the receiver extension. Virtually all other enclosed muzzle devices actually act like psuedo-suppressors with regard to gas pressure; they increase gas system pressure and some can even cause gas-to-the-face situations like a suppressor can. This reduces flash, muzzle rise, and does it while keeping that smooth-shooting nature of my Rainier Arms Mountain Series 18" gov-profile barrel with rifle length gas system. I can say without reservation that it over-delivers.

Less flash on my 18" barrel than an A2 even with Tula steel-cased ammo. Highly recommended! (Posted on 11/19/2014)
