Yea, I missed out on H Y C A P S, saw they site but didn't have the funds, then when I did they vanished - still don't actually know what happened there, seems they got shut down.
I've seen the YouTube vids on converting Uzi mags, I have a few to experiment with - just haven't got round to it yet.
I've contacted IRUNGUNS and they said they'd be taking mags/parts orders once they were set up for canadian credit card payments on their site, though they didn't acknowledge my question regarding pinning the mags.
High Calibre Services, the CGN sponser, said they'd be getting any and all ProMag mags including 9mm AR, pinned, from early next year - perhaps effectively replacing H Y C A P S.
I figure if we all keep barking about this, eventually a dealer will sniff out the business potential and start bringing in the product.
