Barrel extensions and flash hiders provide another layer of tactical awesome sauce. Barrel extensions are external upgrades or add-ons you can utilize to change the look or configuration of your airsoft gun. They look very similar to silencers but provide little to no sound suppression. They go over the tip of your gun's barrel giving you the option to installing a longer airsoft inner barrel that can increase the airsoft gun's range, accuracy, and FPS. Or for those looking for that stealthy tactical look. Flash hiders are the barrel tips for those looking to change out their standard one for a more interesting or aggressive styled one.
