Precision Armament AFAB® Hybrid Muzzle Device 5.56mm/.223 1/2×28 Thread


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″.


  • Matrix of vents that slowly cool and diffuse combustable gases to reduce recoil, muzzle rise, and flash
  • Optimized for performance on 16″ and 14.5″ AR style barrels
  • Closed bottom to reduce dust signature when shooting traditional prone.
  • Precision machined from heat treated stainless steel with an advanced Ionbond® high temperature CrCN coating for extreme durability.
  • Superior Value
    • Value driven design that incorporates EFAB® design concepts with improved manufacturability to provide
      excellent performance on standard length barrels at a much lower price point. Provides recoil reduction* and
      flash suppression performance within 5-10% of the EFAB® on 16”+ barrel lengths at two thirds the price.
  • AFAB® Patented Technology
    • A deep exterior diffusion grid allows combustion gases to both cool and diffuse resulting in effective flash
      suppression, excellent recoil reduction, and minimum concussion to the rear and sides of the shooter.
  • Off-Axis Venting
    • Vent holes are CNC milled off-axis allowing gas to be directed slightly upward while preserving internal
      baffle symmetry for exceptional muzzle control, minimal ground signature and improved accuracy.

*Recoil reduction measured on high precision recoil pendulum from a 16″ barrel using 55Gr FMJ .223 Remington.

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.

Should I choose the AFAB or the EFAB?

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.

*Caution: Do not use crush washers with this product.
