Re: considering a suppressor
If you buy a .223/5.56 suppressor, it'll work on a .22 LR as well. The pressure generated by the .223 will destroy a silencer designed for the .22 LR, so don't try it. But the other way around is fine.
And like Soundguy said, the silencer can be mounted on whatever you want. As long as that thing is something you own legally, of course.
