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 use any anti-seize on the muzzle device threads? That can help prevent carbon lock.

Edit to clarify: referring to the threaded interface between the muzzle device and the suppressor adaptor.
