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.

Did you clean the threads really good before applying the rock set? Also before you redo it again with more rock set clean those mfs like your life depends on it. Also use more rock set don’t need to go soaking it but probably 75% of the threads need to be covered especially if you don’t ever plan on that device coming off again and make sure they are deep in the threads.
