so I want to build another ar but this time in a large caliber like 300 blackout or 458 socom. I just don't know for sure which one I want. what are the pros and cons of each. can you reasonably suppress a 458 socom I know sons of guns did it but what other company makes a suppressor for it. I know I can get a suppressor for 300 but that is not my only consideration. mostly I just want other opinions on the two rounds and what you would do.
