AFAB Hybrid Muzzle Brake


The AFAB-556 Hybrid Brake is the second generation and replacement for the original AFAB-Mini (discontinued). After over a year of R&D developing the EFAB brake we have decided to revisit and redesign the AFAB to include new learned features to further enhance its performance, particularly flash performance.


Installation of this brake requires the purchase of the Accu-washer alignment system.

Battlefield Performance Without Compromise

(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.

Accu-Washer™ Muzzle Alignment System required for installation to achieve best performance (not included).

Caution: Do not use crush washers with this product.
