BT 08 Paintball Bottle Pouch Molle Woodland Digital Camo
I found it a struggle to get my 68/4500 tank into the pouch. The problem is the elastic band at the opening just barely stretches enough for the tank to slide into the pouch.
There are two things I was disappointed with... The first is that I had to remove the cover from my tank before it would fit into the pouch, and the second is that the stiff backing is far larger than necessary in my opinion (I cut it shorter so it wouldn't hit my arm when mounted horizontally).
