I hear you, I have at switch barrel T/C already, and honestly even that is a little bit of a pain because the nut is so big that the optics interfere with it and have to be unmounted. (I'll clearance the barrel nuts to fix that eventually). I was just channeling some old research and wondering if that would make future reinstallation easier. I'm not planning for regular swaps or multiple calibers so probably I'm just complicating things unnecessarily.
