The other comments about using 1 suppressor on multiple firearms make sense. However, I would be very careful about using a pistol suppressor with any rifle cartridge. Also, do some research into HUB compatible mounting systems. I started out trying to use 1 can on 2 rifles with different threads using 2 mounts (the back end of the can). That was based on bad advice from a guy at Silencer Central. I ended up using the Plan B standard (Omega for Q, Atlas for Rearden, etc.). I now have Plan B compatible muzzle devices on 4 different rifles that share that first can.
I’m not saying Plan B is the only answer. In fact, I have propriety HUXWRX muzzle devices on my 5.56 rifles. Just look into flexibility - how many companies make compatible muzzle devices in various thread pitches. Only 2 of the 4 rifles that share my Banish 46 have the same thread pitch (IOW 3 different sets of threads), and I had to modify one muzzle device because of bad design decisions Marlin made.
