The .750″ Low-Pro Adjustable Gas Block is constructed of 4140 chromoly steel and will fit under ERGO Superlite Rail Systems along with other manufacturer’s rails. Adjustments are achieved with the set-screw allowing you to fine tune the amount of gas allowed through the system for load specific use. Accepts standard gas tube roll-pin but does not include one.
Adjustments are made via a 5/64″ set-screw & a 5/64″ retaining screw ensures the system remains locked, no need for Locktite.
