Hello! I'm new here and I apologize if this is in the wrong area. I recently ordered a dotmod Petri Mech 22mm mod and wondered if a Petri RTA would be compatible. The Petri I ordered has interchangeable floating center pins. Each one is a different size. I kind of thought the pins that you'd use would depend on if the atty had a protruding 510 or not. It's not a hybrid cause I know with hybrids you have to use an atty with protruding 510. If I'm correct it's the original Petri, not the Lite version. I think I can post an image of the mod if needed. Thanks, Kronk.
