Socom Gear guns should either be VFC or G&G OEM from what i know, and i think the PWS model is G&G? not sure but you can probably check.
but +1 to what Stealth Said
tbh you can already pick up a VFC for a tiny bit more since those guns you listed probably will run you at least 350 - 450? not sure but im just Guesstimating :P
but yes G&G seems to be an extremely common all around Canada so you could go for those
