Adjustable gas block allows you to fine tune the amount of gas directed back through the gas tube. Do this for less recoil, slower cycling, cleaner gun and less wear.
 
Our Stainless Steel low profile gas blocks are really light, yet very durable. High Grade Titanium bolts make sure the gas block is attached securely to the barrel.
 
This gas block is adjusted from front. Front adjustment is specially suitable if your gas block is covered by handguard, eliminating the need to remove it first.
