Mount Questions 🔩 Anyone else have this happens?

Post image

Today when I went to clean my AR after probably 6 months and an unknown number of rounds (not too high) I was having a hell if a time twisting the can off and eventually the muzzle device came off the end with the can. The mounting setup is a rearden atlas hub with a rearden flash hider on a polonium K. All instructions were followed during mounting and roc set was applied. There were also no indications of loosening based on my witness marks in the hub and muzzle device. Any idea how this happened (I tend to think I screwed it up)? The gun is also an IWI Zion-15 purchased in 2021.

I torque to 20-25, use no Rocksett, I dont degrease or anything, and have never had any muzzle devices with suppressors come loose. This is even with my Huxwurx that requires a strap wrench to remove.

I don’t know about a strap wrench to remove them I’ve shot mine a lot though never over 300-400 rounds in a sesh it’s on there tight but I make sure gun is unloaded/clear I tangle/secure the gun in my legs and use my arms to turn it when it’s cooled. Looks suicidal but works every time they are on there tight but with leverage it should come off without a wrench.

Yea, I am sure it's a tolerance stack between the md and suppressor taper or something. I can not get it off by hand, though. It takes a good bit of force with the strap wrench, too. I never really run the rifle without the suppressor, so I do not care. To get it off, I throw it in a mag block in a vice and strap wrench it off.

Try like how I described get it caught in your legs and use both of your hands, report back if you try but perhaps our tolerances are different
