If you are looking for a 30 cal rifle can to switch between several platforms consider the SilencerCo Omega. My trust has three of them on it. I use it on a 308 bolt gun, 224 valkyrie AR, 223 AR and a 300blk AR. The back pressure is not bad and I don't have to load anything different except when I want subsonic 300blk or 308.

The Omega can attach with a quick disconnect device or direct thread. It can withstand full auto and up to 300 magnums.

I have been getting a suppressor for each firearm but the Omega still switches between several hosts. Two of the guys on my trust only have an Omega for rifles. They have pistol and rimfire cans but use the Omega for 3 or 4 different rifles.
