So, atleast on my universal nail, a 5/16th socket fits nice and snug on the hole of the nail. Helps me because I only have that small dab rig but now I can smoke bud from it too
Thanks bro! dude I got it at a headshop for $26!! It was a good first piece, I dropped it the other day tho I replaced it with a slightly bigger piece(but not too big) and it's the perfect height for on the go/keeping it hidden.
I'll have to check out my LHS, haven't been there in a while. Nice rig bro, love the scientific glass. Looks like my rig except mine has a smaller neck and fatter base. That's the only bad thing about glass, if I still had all the pieces I broke I would of had a nice collection by now.
