I've been looking for a semi-auto 22 and of course came across the Ruger 10/22 just like 'lildave' - it definately appears to be a favourite for performance out of the box, but more so due to large number of readily accessible & relatively 'cheap' upgrades (target barrels & sport stocks, extended mags, improved triggers, even entire receivers/frame upgrades). It seems that you can even get a lot of this stuff as stock items through Canadian 'hunting' supply stores (e.g. Bass Pro & LeBarons). But... a lot of the high-end target conversions and other stuff I've seen on the internet don't appear to be standard stock in our 'sporting goods' stores (in particular, mods that would give the 10/22 a 'mini-assault' rifle appearance like folding and bullpup stocks, muzzle brakes/suppressors, etc.) -> so my quesion is: assuming your end-result isn't less than 26.5" total length (i.e. which would make your 10/22 'restricted'), what are the current legal and logistical realities of ordering parts from the USA - what's being stopped (legitimately or not) at the border? Will a 50 round magazine make it across? What about a folding stock? Or a receiver? How well versed are our customs officials on the finer points of what is and isn't legal? Any comments appreciated.
