So I am in the market for a can for the XCR. I currently have 5.56 and 6.8 with more coming. I would like to be able to supress the 2 of them along with the .308 when it comes out. Is it unrealistic to get a can that can handle all of them or would I be better off buying 2 different cans (i would think .308 and 5.56). THanks guys.
