Description
The United Defense Labs .750 Adjustable Gas Block is designed to fit under most manufacturer's free float handguards. Adjustments are made via a 5/64 set-screw and a 5/64 retaining screw ensures the system remains locked, no need for thread locker.
What you want to achieve is a rifle that functions correctly with the proper amount of gas pressure.
This is done by adjusting the amount of gas into the system. When this is done it should be with the actual load you plan on shooting. Too little pressure going through the system and the rifle will not be reliable and too much will cause excessive recoil and could damage your rifle.
The adjustments must be done in a safe area following all safety rules. "Make sure that the firearms is completely unloaded"
