Best block ever! - Superlative Arms Adjustable Bleed Off Gas Block

This is by far the best adjustable gas block made. Ive tried alot of adjustable gas blocks. Most will seize up pretty quickly. Their bleed off system works great for keeping the adjustment screw from seizing. There is a huge adjustment range to dial in your gas which is vital to reducing felt recoil. I was able to go with a lighter buffer spring and bolt with heavier buffer for a super reliable almost zero recoil setup. If your looking to fix overgassed harsh recoiling ar this is where you start. Forget about heavier buffer springs to fix overgassed guns. Fix overgassed guns by fixing the gas!
