Most Helpful Positive Review best version yet
Installation now is super simple. I have both law tactical folders and previous generation sylvian folders. I believe gen 4 sylvian now surpasses all of them. Definitely a great mod to ar. Just makes sense. More rifkes should come out of manufacturing with folders installed.
Most Helpful Negative Review Do your homework
Be careful if you are planning on using this SA folding adapter with the JP silent capture buffer spring! In  two places in the description is says it work's with it. "Compatible right out of the box" and "includes a bolt extension compatible with the JP silent capture spring" I found out neither of...

Great product works well

by Brock, Verified Owner from WY, United States Written on February 2, 2026
This product works flawlessly and came with all the tools required to install it. I saw another review that mentioned the product did not come with any instructions. Either they have updated the packaging, or that person missed the QR code that links to an easy-to-follow installation video. I defiantly recommend this product to anyone looking for a cost effective folding stock adapter for the AR platform.

Adds 1.1 ounces to the BCG

by Dan, Verified Owner from MO, United States Written on July 23, 2025
Folding is not the issue, there is an aluminum bolt extension included with this stock adapter that adds 1.1 ounces to the BCG which is no big deal if shooting supersonic rounds but may affect the cycling with pistol length gas systems shooting 300 blackout subs.

These are badass...

by joshuah, Verified Owner from OH, United States Written on July 9, 2025
I'll be buying more. Love how my AR9 PCC fits into my backpack now. Very well made. Very much worth the coin. There's already another one in my cart lol. Safe shooting! have fun! If you are buying this for a 9mm ar you will need to remove the weight in the rear of the bolt. Held in by one pin. That way the bolt extension fits right in there for proper function. No you cant fire it when its closed even though my buddy said yes you can but only once... ill pass lol.
Pros:
  • well made
  • EASY INSTALL
  • Made in USA
Cons:
  • None
