The Superlative Arms Patented “Bleed Off”, direct impingement, gas block for the AR-15/AR-10/LR-308 platform adjusts the gas flow by bleeding the gas out of the front of the block instead of restricting the flow like conventional adjustable blocks.
The pressure used in the block is reduced only to the amount required to drive the bolt carrier. The remaining gas and pressure are bled out of the block allowing the system to run much cleaner and cooler.
Reduction of wear on the bolt carrier group components.
Reduction of felt recoil allowing for faster follow-up shots.
Patented adjustment detent is located outside of the block and therefore no contamination.
In bleed off mode the gas adjustment screw does not restrict the gas flow; therefore, there is no erosion or seizing of the screw, and no loss of detent due to carbon build up. Although it is removable, we have added a safety mechanism, which stops you from unintentionally backing the screw all the way out.
When using SBR’s and/or suppressors the bleed off port allows the excessive pressure to be exhausted out of the block reducing blow back.

The set screw immediately stripped on me I even had to order new one, shocked how easily messed up it went and I been working on guns for many many years.

Fit, finish and quality are outstanding, they live up to there brand name Superlative. I have placed one off these on everyone off my builds and they all sing like a sewing machine once dialed in.
Sizing out of spec and burr left on gas port hole, disappointed.

I've used a few of the Superlative Arms Adjustable Bleed Off Gas Blocks in the past for rifle builds, but this most recent one had some issues and when I attempted to reach out to the company, they were closed for a week and I was in the process of a build. The gas block has a small burr where gas port was drilled, which marred the forward section...Read MoreRead more about I've used a few of the Superlative
of the gas journal on the barrel and unfortunately was not covered by the gas block (or the handguard) after eventual installation. The gas block itself was also slightly undersized and would not fit over the gas block journal on the barrel. I double checked the gas block journal with three other gas blocks from two different companies that I had on hand for other builds and all fit. Ended up having to use an abrasive to gradually remove material from the inside of the gas block to get it to fit for the install. Read LessRead less about I've used a few of the Superlative
