Precision Armament EFAB is an advanced hybrid exhaust device for the AR-15/10.
Why Hybrid? Because it effectively combines the best features of an exhaust brake, a toss compensator and a flame suppressor.
As a result:
- matches or exceeds many exhaust brakes in recoil reduction (at 56% for .223, 45% for .308)
- almost completely eliminates recoil, with full barrel neutrality during firing
- can be used in full comfort when shooting in a recumbent position, against curtains or in tight spaces, and the discharge flame is less than that of a standard A2 flame suppressor.
This was achieved through advanced simulations of the exhaust gas flow. These allowed the exhaust flame, noise and gas blast to be optimized for reduction.
The EFAB 556 is designed for optimal performance on barrels with lengths, in the 10″-14.5″ range. Installation on barrels shorter than 10″ is not recommended.
Note: Crush washers are not recommended for mounting the device.
For brake installation, it is recommended to use Precision Armament Accu-Washer or other rigid washers.
