After swapping out your barrel for a shorter one, did you guys call the CFC to update your registration certificates? Did you have to get it re-verified? The registration certificate for my 10/22 states "Barrel Length 470mm or greater".
Doesn't it say somewhere that you only need to notify them of changes in calibre and changes that affect its status?
Believe that is so. however, having the short barrel info on a certificate may save you a hassle and time wasted if you are ever stopped by an LEO who isn't as conversant with the rules as you are. Also, I don't beleive a change of calibre affects its status ( restrixcted, non restricted, or prohibited) either.
change of caiber could effec it if you changed it to .25 or .32
all guns chambered in .25 auto or .32ACP are prohib and you need a 12.6Sorry to hi jack, why are these calibres a no no? .25 or .32

plus you cant get any new ones of them, unsure where rechambering a gun for them would fall though
