Precision Armament built the EFAB (Enhanced Flash Arresting Brake) to tackle two jobs that usually fight each other: taming recoil like a brake while hiding flash like a flash hider. This 762 Hybrid handles both on .308 and 7.62 NATO builds with a 5/8×24 thread, and it pulls it off even on short barrels down to 10 inches. If you've ever had to pick between a flat-tracking brake or a dark muzzle, this is the device that lets you quit choosing.
The magic is in the internal geometry. A configuration of diverging expansion nozzles cools and diffuses combustion gases, which cuts recoil and keeps muzzle rise in check while knocking down flash at the same time. The vent ports are CNC milled slightly off-axis so gas gets directed a touch upward, helping the rifle track flat during rapid fire without throwing off baffle symmetry. The result is a muzzle that stays put and a signature that stays low, which is exactly what you want in low-light or close-quarters work.
This one is machined from HTSR 416 heat-treated stainless steel bar and finished in a matte black Ionbond CrCN coating, so it shrugs off the heat and abrasion that come with heavy shooting. It measures 2.750 inches long and 0.985 inches in diameter, tipping the scale at about 4.25 ounces. The closed bottom is a smart touch for anyone shooting prone, since it keeps gas from kicking up a dust cloud and giving away your position.
A couple of install notes worth knowing. Precision Armament recommends their Accu-Washer alignment system for timing this device, and it's sold separately. Skip the crush washers on this one, as the manufacturer specifically warns against them. The brake also comes with a pilot hole drilled for permanent pinning, which is handy if you're running a 14.5-inch barrel and want to pin and weld to reach a longer overall length.
It's threaded 5/8-24 for .308 and 7.62 NATO barrels, which covers most .30 caliber rifles and AR-10 style builds. Precision Armament designed it to stay effective even on barrels as short as 10 inches, so it's a solid pick for short-barreled rifles too.
No, the manufacturer specifically warns against crush washers with this brake. Precision Armament recommends their Accu-Washer alignment system for proper timing, and that's sold separately. Following their install method keeps the ports oriented correctly for the best muzzle control.
It's genuinely both, which is why they call it a hybrid. The EFAB uses diverging expansion nozzles to cut recoil and muzzle rise like a brake while cooling and diffusing gases to suppress flash like a flash hider. That combo makes it a strong choice for low-light and close-quarters shooting.
Yes, it features a pilot hole for permanent pinning. That makes it a practical option if you're running a 14.5-inch barrel and want to pin and weld to bring the overall length up. You'll want a qualified gunsmith to handle the pin-and-weld work.
