Every summer I buy another suppressor. Last year, I got my first rifle can (762-sdn-6). It generally sits on my .300 BLK SBR. I just ordered the last parts I need for my 5.56 SBR, and of course I want to suppress it. Question is, do I go for a dedicated 5.56 can, or do I get another .30 caliber can and use it on the 5.56? It seems that a .30 cal can does a very nice job of suppressing 5.56. Am I wrong in my thinking?
