AFAB (Advanced Flash Arresting Brake)

Combines the performance of both a dedicated flash hider and a dedicated compensator. Patented AFAB™ technology employs a complex matrix of tiny passageways that slowly diffuse and cool combustion gases so you can stay on target during rapid fire engagements while effectively suppressing muzzle flash and side concussion. Closed bottom design 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 3/32" pilot hole for permanent pinning to bring 14.5" barrels to legal length.

The AFAB is designed to fit .223 caliber (5.56mm) AR-15/M16/M4 style rifles with 1/2-28 muzzle threads. It is not recommend to use this device on barrel lengths shorter than 14.5". For SBR's & pistol length barrels please see our EFAB device.

Caution: Do not use crush washers with this product.

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. For a more detailed explanation and examples, check out our Caliber Fit Guide.

At 16", the EFAB has a marginal advantage in both flash suppression and recoil reduction compared to the AFAB.  When measuring barrels at 14.5" and below, the EFAB has a substantial advantage, and maintains that performance down to about 10". Therefore, we recommend the EFAB for most applications utilizing SBRs, AR pistols, and bullpups. For 16"+ barrels, the performance difference is close enough that the decision can really come down to user preference.
