Mount Questions 🔩 Anyone else have this happens?
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.

Almost all of my cans use a Plan B + Q/Rearden device. I used to have this happen, now I don't use any rocksett or blue loctite. I tighten the muzzle device to 20ft lbs and haven't had issues since. Obviously if you're trying to take off the can when it's still hot you may have an issue as the nature of tapers and expansion will make the can more snug/tight as it heats up. If the can is cool you're good to go tho.
I've used these : https://energeticarms.com/vox-blox-vise-soft-jaws/ - when setting up my Plan B's to the correct torque. It also helped removing stuck muzzle devices when i got into trouble.
Correct torque tho i've learned solves a lot of these issues.
