Gold plated brass
Protruding 510 pin, safer to use on hybrid mechanical mods
New bottom feeder pin design, no need to remove the 510 pin to interchange from bf to non bf mode. Easily remove or install bottom feeder plug (flathead screw) from the 510 pin directly & simply store in the pocket integrated on the deck. The round head of the flathead plug creates a tight seal against the 510 pin cavity which makes it literally 100% leak-free when in non bf mode. Optional micro gaskets for the plug is included and can be used with or without.
