The Superlative Arms patented "Bleed Off", gas piston system for the AR15 platform adjusts the gas flow by bleeding the gas out 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 / pressure are bled out of the block allowing the system to run much cleaner and cooler.
Reduction of felt recoil.
Patented adjustment detent is located outside of the block and therefore no contamination.
The gas adjustment screw does not restrict the gas flow; therefore there is no erosion or seizing of the screw / 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.

Gas block is larger than many others, may cause interference.

The piston system itself works flawlessly. My complaint is with part compatibility. Given the size of the gas block, I could not get it over my Aero Quantum rail, so a little creative cutting was needed to make it work.
Review by Edan P. on 30 Jul 2021review stating Mine didn't fit, that doesn't mean yours won't
I was unaware of the product's sizing for a barrel, and it would not fit mine. The block was 1/16" too small. However, the build quality was very nice, and all of the components were likewise. I would recommend anyone who wants to retrofit their AR-15 get this product
