On top of that, going back to the same settings can be difficult like when switching from suppressed and unsuppressed configurations. Remove the hassle but keep the functionality with Strike Industries’ innovative adjustable gas block. Using 5 pre-sized settings and 1 closed setting, easily return to the exact same level of gas flow for your direct impingement system. The gas block easily switches position by rotating the collar by hand or while it’s inside a hand guard with a bullet or blade.
