Is this a conversation kit or only for already existing piston system guns

Do you have chome bolt carriers

Helpful Positive Review The Superlative Arms Adjustable Piston System is a great choice for any build or as an upgrade. by Shoop, Verified Owner, November 27, 2022

Helpful Positive Review Good option for DIY piston conversion by Dan, Verified Owner, August 12, 2023
Pretty easy to install. I liked it so much on my 5.56 I picked one up for a 300 blackout build. The big downside is its a little pricey and you still have to pick up a bolt group. There are some good YouTube videos out there that will answer any q...

Features of Superlative Arms AR15 .750in Solid Adjustable Piston System

  • 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 and upper receiver.
  • 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 SBRs and/or suppressors the Bleed Off port allows the excessive pressure to be exhausted out of the block reducing blow back.
