So I want a center fire rifle can. I really want a can with an A2 mount so I can run it on all my ARs without having to spend a bunch on mounts for all of them. I don't have any 7.62 stuff but I do have plans on getting a 7.62 bolt action something at some point. My LGS has ben trying to get me to get a 7.62 can and just skip the 5.56 can altogether. But my question is why? If I do go 7.62 at some point I would probably want a direct thread and just leave it mounted all the time. What say you guys? Am I missing something to my logic?
