5-Prong QD Flash hider

Silent Steel 5-Prong QD Flash hider is a suppressor mounting muzzle device. The prongs are connected to each other at the muzzle of the flash hider. This makes the prongs stronger and there is no risk of prongs bending. The monolithic prong design prevent prongs to ping under fire which is quite common feature of prong type flash hiders.

For short barreled rifles (10″-12″) we recommend A1, A2 or 5-prong Gen 2 flash hiders for maximum flash hiding.

The 5-prong flash hider has been updated to Gen 2 model. Gen 2 is compatible with BFA devices and it has improved flash hiding. Gen 2 Currently available in 1/2″x28 and caliber 5.56.

More info:

Taper at the front of the thread ensures solid lock up and minimal/repeatable POI shift and it also effectively blocks fouling from entering the mounting surfaces.

The heat resistant o-ring behind the thread secures the suppressor tightly on the flash hider and suppressor will not loosen up by itself. The heat resistant o-ring peak temperature resistance is 400c degrees. In our test the muzzle device temperature, with AR15 equipped with 5.56 Compact Streamer, was 280c degrees after 6 x 30 rounds magazines in row.
