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

Worked well with FRT

by Dan, from WI, United States Written on July 23, 2026
Got this for an AR pistol build that had a Triggered Co. Disruptor FRT in it. Wasn't sure if the BCG extension or the overall folding mechanism would cause issues with the FRT functionality. Low and behold it did not have any issues and the FRT functioned flawlessly with the Sylvan set up + a H3 Buffer. Highly recommended especially for a compact FRT gun.
Pros:
  • EASY INSTALL
  • works with FRT
Cons:
  • None
Would recommend: Yes
