Smitty, I am waiting on my stamp for the one I purchased from Major Weapons. I read an article that compared all types of "Cans" and for my purposes, it fits all my needs, .308, 300 blackout and after doing some research. I can order another quick detach mount with different threads.
I went on YouTube, and there are some sites that have side by side comparison.
Once my stamp arrives you are welcome to try it.
