The OG Recoil didn't have a squonk pin/post, historically. Just last year they released a limited run of OG Squonk Recoils, which were "squonk only" -- due to the way the post is, they were specifically drilled out and squonk pin installed for this reason. There's no normal 510 pin. This is the understanding I've gathered from the Namberjuice group on FB, and because I ordered and own one of those.
So I guess what I'm saying is that you might get a bit more traction posting a "WTB: Squonk OG Recoil" or something similar, as the only squonk pins available are either custom-drilled or from the batch they sold last year.
