Surefire is just my personal preference, but I like to get anyone else's opinion on any other cans. I'm looking for a universal, interchangeable 7.62mm surefire can, so that I can use "one suppressor" for my M1A which is chambered in .308, and my Remington 300 WM which is also takes a .308 diameter bullet. I just thought that the FA762SS can from surefire might be a good choice . So, to find out more information, I contacted surefire's tech, Greg. And he said that there 7.62 suppressors are rated up to 300 WM and that the higher pressure of the magnum won't hurt it. And if anything "should" happen, and the suppressor is damaged for any reason , it'll be covered under their life time warranty . Just good info I wanted to share.
