MadBull Airsoft fully licensed GEMTECH HALO mock suppressor "can".
The HALO is rock solid, easy to use, and requires no modification to the host weapon. It utilizes a simple, patented, no-tools mounting system that slips over most 5.56mm style flash hiders. There is no need for proprietary mounts or modifications to the barrel. It may be swapped between many different weapons easily, including but not limited to M16, M4, HK416, and M249 weapon platforms.
Give your rifle a more aggressive and "quiet look". Make it flush with your rail system or handguard and get that flush SD look.
