Where can I order model gun replicas?

[inlayterms]

When I was a teenager (about 20 years ago), I purchased a model gun replica here in Toronto. The model contained all the parts of a gun (the inside parts were made of metal and the outside parts were made of ABS plastic). Once built, it was truly impressive and, aside from not being able to shoot anything, functioned like the real thing (e.g. semi-automatic, ejecting shell casings, etc.). Recently, I've been wanting to find another one to build again, but am unable to do so - probably for legal and safety reasons (i.e. they look like the real thing). Does anyone know if these model guns are still being manufactured and, if so, where I can order one? Also, does anyone know if there would be any legal restrictions on importing one to Canada? Thanks.
