Boy did you guys miss the point. I was seeking clarification for those who want to have both options available for this mod. The OP chose one way, Which is ultimately the way I want to go as well. But there was also claim made that modifying the mags to fit the magwell without milling the receiver would make it prohibited. I cant find anything in the regs that states that to be the case, so i asked the firearms tech department for clarification. The seller of the adapter seems to think that modifying the mags in the way that they do is totally legal so long as you do not increase the capacity. So props to the OP for all his hard and totally 100% legal work and willingness to share with the community.
I was doing this as a public service to anyone who wants to try this themselves but did not want to mill the receiver. In somewhat typical fashion a couple of you clearly have reading comprehension issues.
So once more, I am seeking the clarification of weather or not is is legal to leave the rifle whole and instead modify the mags for fitment from the RCMP. I will be informing in this thread the outcome of my inquiry. The rest of the peanut gallary can friggin cram it unless you have something constructive to offer.
One very important note:
The seller of the adapter is in the
United States of 'Merica. Not Canada. I'm sure he's a great guy, but you can probably assume that when he thinks it's legal to mod mags... those legalities would be related to the
US'M. Not Canada.
I believe the root of the legal issue with modifying magazines in Canada would be that you're in a (EDITED) situation of manufacturing a prohibited device. (It may be put forth by legal authorities that you're making a 10 round magazine to fit an SKS.)
On the other hand, I don't know of any legal language that prevents you from modifying (for cosmetic or other purposes, who cares if you call it "SLAG" or not?) the base rifle to accept different magazines... ok, so those magazines happen to be 10 round pistol mags, who cares?
This is evidenced by the existence of mag adapters for the VZ58. You're not changing barrel length, or overall length, or making it full auto... You should be good to go.
So basically chop your rifle all you want (again, outside of specifically mentioned items relating to barrel length/OAL or FA).
I guess what I will say is: We don't have a verifiable "green light" to modify mags specifically to fit different rifles... So when you chop on a mag (manufactured and designed for an XCR pistol) to make it fit an SKS (modified or not), what do you think you are doing, exactly? It could be easily put forth that you're mfg'ing a 10-round SKS mag. (Therefore a prohib device).
There's lots of room to prove me wrong, though. I'm definitely not a legal encyclopedia.
Considering the 10-pack of mags from Questar is more expensive than the SKS, I'd rather just mod the SKS anyway!
EDIT:
And also, by calling the RCMP and asking them if it's OK to remove metal from a magazine is just muddying the waters.
If you need to trim some sharp edges, tweak your feed lips a bit, replace a follower to enhance function in the firearm it was designed for... I do believe that is quite legal. (Am I wrong?)
If you start modifying for the purpose to fit it to another firearm... well then...
