I love this thing, but it has a design flaw. There are no flats to tighten it. I put blue loctite on and tightened it by hand. It cured for a day before I put 40 rounds through it. It was rattling when I got home. It wasn't spinning off, but it was loose. I could use red loctite, but even red can be worked with if you apply enough heat. I probably won't heat it up enough, but anyway. One can out there has slots in the outer lips of the can so you can use some kind of tool to tighten it. I just cleaned up the threads and dumped a ton of blue loctite on the threads and hand tightened again, but it's not going to work. I'm thinking some kind of strap wrench like an oil can wrench, but it needs to be much smaller. Any ideas?
