We have always been fans of the effectiveness of open prong flash hiders which have proven more effective at flash reduction then any of the closed end brakes.

Our 9315 flash hiders are aesthetically modeled after the HK93 4-prong open flash hiders, hence the 9315 designation.

We have 2 versions: 3-prong and 4-prong.

The 3-prong allows for more material in each prong, giving greater strength in case of hard impacts.

The 4-prong allows the user to also employ the flash hider as a wire cutter if needed by placing the strip of wire between the prongs.

Both are very effective for flash reduction and the difference between the two seems negligible in effectiveness. Machined from 4140 and black nitrided for corrosion resistance.
