Ah...tricky one.
Should obviously be non restricted, but......being an evil AR derivative it has to be restricted as with other AR .22's.
HK .22's that mimic the MP5, HK91/93 are prohibited in Canada. This looks exactly like an HK416, only the magazine gives it away and that would make it restricted.
Now that's my logical assumption, which does not apply to canadian gun regs of the day/year/mood, etc. So just vote conservative, support the canadian gun lobby, pester your MP - politely, and pray and wait, wait, wait.... hey when are those MP44 style rim fires getting here?!
