Superlative Arms Adjustable Piston Conversion Kit – .750″

Piston Conversion Kit – Low Profile, Adjustable, Forward Venting “Bleed Off.”

The Superlative Arms patented “Bleed Off” Gas Adjustable Piston Conversion Kit / 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. Results:

  • 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.
  • The patented adjustment detent is located outside the block, with 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 that stops you from unintentionally backing the screw out.
  • When using SBRs and/or suppressors, the bleed-off port allows the excessive pressure to be exhausted out of the block, reducing blowback.
  • Available in Pistol, Carbine, Mid-Length, and/or Rifle Gas configuration.
  • Select your mounting style – Clamp-On or Solid (Set Screw).
