The Superlative Arms Adjustable Gas Block is designed to give you a near endless amount of adjustments for tuning your rifle to be low-recoil and reliable. However, unlike conventional adjustable gas blocks, it does not restrict gas flow but redirects it out of the block, so only the exact amount of gas required to work the bolt is used. This bleed off style offers many improvements like a cleaner and cooler running rifle as well as better functionality in SBRs and suppressed rifles. Because of the bleed off port, the excess pressure cause by suppressors and short barrels is exhausted forward reducing the amount of gas blow back to the face. The Superlative Arms .625” adjustable gas block uses the clamp on attachment method on barrels with the same diameter gas block journal. If you plan on shooting suppressed, building an SBR, or just want a better shooting rifle, this is the gas block for you.

This Superlative Arms bleed off gas block features a low-profile design, so that you can use most free float handguards with it. Also included is a 6” hex key for adjusting the gas block while it is underneath the handguard. With 30 adjustment settings, you can easily find the sweet spot to reduce felt recoil while staying 100% reliable. Because the adjustment screw is located outside the block, you do not have to worry about carbon build up seizing the screw or high pressures causing it to erode. Machined form 416 stainless steel with a matte finish, you can bet this gas block will last a long time.
