Beautiful machining but hard to fold.

by maiti, Verified Owner from LA, United States Written on August 13, 2025
This is a beautiful piece of machining - both the SF-6 and the folding mechanism. The stock locks with almost no play.

Unfortunately, I could not fold it with hands even after watching the JMAC video available online. I need to put it at the edge of a table and lean heavily against it to lift up against the spring and fold it. There is no need to put such a strong spring, maybe I got a bad one. This is by far the hardest one to lift against the spring and fold compared to some other makes I have used in the past.

This is the reason I had return it.
Pros:
  • well machined
Cons:
  • Hard to fold
Would recommend: No

Best 1913 setup

by HangryAlpaca, Verified Owner from TX, United States Written on August 6, 2024
I've been looking for the best 1913 brace setup and between this and the aluminum sb tactical brace this beats it by far imo. I would give the aluminum sb tactical brace 2nd place. This tube is sturdy! 0 play..

Well-made sturdy folding option

by Just an average Heckler, Verified Owner from TX, United States Written on June 21, 2024
Ideal for brace options using piston systems. Jmac always provides solid stuff.

  • Craftsmanship, built to last
Cons:
  • price

  • Battle rifle and hard use
Would recommend: Yes
