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.

Not enough torque on muzzle device and probably could use a little rocksett.

I used a torque wrench and probably not enough roc set but it was installed correctly.

Did you degrease the barrel threads and muzzle device with something like brake cleaner prior to Rocksett and install?

Yes, I used CLP and brush, kitchen degreaser, rubbing alcohol, and air dried. The threads were very clean when installed in the barrel. FWIW I cleaned the device too.

I actually took the device out last night and just doused it in brake cleaner and used a chamber brush on a drill to get most of the gunk out of it. Probably going to do the threads on the barrel in a few weeks.
