can't do that with an AGR tank, the bottom hole is only big enough for the 510 connectin threads to go through.
what do you do when the juice level falls below the feed holes level? in an AGR tank there is a good half an inch of juice left down there.
this question is specificatly for the AGR tank but I appreciate the response firestorm.
It sounds like you have your terminator set in the tank so that just the threaded part of the 510 connector is sticking out the bottom of the tank (so it sits flush on the top of your mod.)
If you push the Terminator into the tank all the way down, so that the bottom of the bulb is flush with the inside of the bottom cap, the "intake ports" where the 510 extender and the "bulb" come together with be pretty much flush with the bottom of the tank, and you should, theoretically, be able to vape it almost dry.
Of course, your 510 extender will stick out a little farther from the bottom of the tank, so it won't sit flush on the top of your mod, but I think a visual gap of 1/8" between your mod and the bottom of the tank is an acceptable compromise for being able to get every last drop of juice out of your tank, if that is what you are trying to do.
If a gap between your tank and your mod is simply intolerable, then I would suggest getting a hybrid... ;-)
