This 3-prong flash hider is compatible with the Saker MAAD Trifecta mounting system. It offers one hand on one hand off attachment/detachment. The patent-pending resonance suppression effectively eliminates the tuning-fork effect common with competing 3-prong flash hiders. 1/2 X 28 threads for 5.56 and 5/8 X 24 threads for the 7.62 version.
