Best 308 Flash Hider - Editor's Choice

There are two types of their operation: either concealing the flash or reorienting the burning gases muzzle flash through holes or slots in a muzzle device.

Why do we need a 308 flash hider?

The flash hiders ensure the shooters with minimal flash while weapon firing, decreasing the shooting smoke and enhancing visibility. They slightly mitigate recoil, but not as effective as compensators. The flash devices also allow dispelling the kicked-up dirt amount while shooting from a prone position.

How to Install 308 Flash Hider

  • If you want to install a silencer on the flash hider, don’t use a crush washer, which can cause alignment issues and result in a baffle strike, just shoulder it against the barrel.
  • During the mounting-dismount unload of the rifle, it should stay empty.
  • Check the threads of the barrel and the flash hider, clean them if necessary.
  • As grease helps the device hold in place and maintain the pressure to the spring tension, apply a few drops on the washer to decrease friction while turning.
  • A crush washer for flash hider isn’t a usual one, it is considered to be a cone-shaped spring that clamps, and at 1/4 turn keeps a 20-28 ft/lbs rotational torque till totally flat.
  • The mated surface needs to be the same or bigger than the crush washer contact diameter. The thread profile comes with a proper compression diapason to the muzzle threads.
  • Put the washer over the muzzle threads, screw on the flash hider against the washer, and hand it tightly. Swing the device 1/4 turn (about 90 degrees) a bit to clock it duly with a suitable tool or wrench.
  • Before shooting, check the due gripping screws’ torque and the flash hider position.
  • Inspect long-shot strings every 50 shots, to ensure proper rifle operation.
