Jmac 360 on criterion barrel 5.56

by Fullbach, Verified Owner from WI, United States Written on April 26, 2025
I mounted this on my 12.5 5.56 ar with a criterion barrel. You do have to time these breaks so the ports are in the correct position to reduce recoil. Fortunately that’s pretty easy, then add a little rock set and you’re ready to attach your hub compatible suppressor. This is a far cheaper solution to most mounting systems not to mention a bit lighter too. It’s pretty seamless! I have been looking for a simple and cheap mounting systems and after looking at all of the options this is the route I’m going.
Pros:
  • Light, cheap easy instal
Cons:
  • Must be timed with shims
Best Used for:
  • Hub suppressors and suppressor use
Would recommend: Yes
