The Superlative Arms Patented “Bleed Off”, direct impingement gas block for the AR-15 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 & pressure are bled out of the block, allowing the system to run much cleaner & 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 & 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 & no loss of detent due to carbon build-up. Although removable, an added a safety mechanism stops you from unintentionally backing the screw out entirely.
  • When using SBR’s &/or suppressors, the bleed-off port allows the excessive pressure to be exhausted out of the block, reducing blow back.
