An odd Question

[Double Tapper]

I think some ppl are miss understanding what I am tring to do here.
I am making an adapter to do away with the shells and just use AEG
mags.

As for more gear,it depends on how much C02 is used per shot.With
the regulator bringing the pressure down quite abit,it should last
awhile longer,about the length of a mini batt.

Switching out the tank in the stock is about the same as a batt.
swap.And we mostly play at paintball fields,so C02 is almost always
at hand.

The barrel I'll be using,is a TM stock barrel put inside an adapter tube.
The hop up will be atached to the adapter tube.

This is something I want to try and see if it works
