this is the classification:
From FRT:
"prohibited firearm" means
(c) an automatic firearm, whether or not it has been altered to discharge only one projectile with one pressure of the trigger
That is the prohibition that applies to CAs.
I'm presuming that the specimen submitted had been scratch manufactured as semi. If it was a remanufactured FA gun, then the classifiaction is correct under the law.
The VZ58 type rifles come to mind: they were manufactured using brand new, never assembled, selective fire receivers, altered to semi prior to being used in a rifle. This concept was specifically approved by the RCMP.
Does it really matter?! In the end 'they' do whatever 'they' please.
I will have a meeting with the manufacturer at IWA in March. We will be discussing possible re-design to get PKSK classified as restricted.
