    Great product. I was confused at first of how it went in the bolt. I got it right the second time.

    Not compatible with Sylvan Arms AR Folding Stock Adapter

    Posted by Brian on July 16, 2022

    This extension is apparently not compatible with a Sylvan Arms ARH300 AR Folding Stock Adapter and a 9 mm bolt with the weight removed. The bolt is not pushed all the way forward by the buffer and spring to fully chamber a round.

    I’m running a law folder with a 4.5” 9mm set up. Works great added 2oz of buffer over my old pdw stock set up

    Essential for 9mm LAW folder builds

    Posted by D. on July 8, 2020

    Using a LAW folder on a 9mm blowback required removal of the heavy internal bolt weight to make room for the LAW bolt extension stub in the hollow end of the bolt. The original extension stub weighs significantly less than the removed weight. This longer heavy extension brought the 9mm bolt back up to proper mass for blowback operation. Perfect fit and function. Thank you, KAK!

    Perfect!

    I was really hoping someone would come up with these. Leave it to KAK! If you want a really compact 9mm build, get this to use with a LAW Folder. Rock solid.
