Tank With Stock & Adapter, 13 cu in, Aluminum, 3,000 psi, Black

It's nice to be able to convert a 90gram CO2 and you certainly can save money filing your own tanks.

Air volume capacity, regulated, easy to fill and gauge makes it all work.

I really like this air tank system. It'll save money on Co2 bottles and allows for considerably more shots per fill. The cost will quickly be covered in savings from not having to buy cylinders. The system is very well built, I fell very comfortable filling the tank with 3,000 lbs of air. And just a side note, I found an outfit that sells bu*+ stocks that fit on the 2" tanks perfectly. They have several models in multiple colors. I put a tan one on my Sig MCX and a black one on my Sig MPX. Very pleased, thanks you so much.

Nothing! This is a waste of time and money, and for $100 is an absolute joke! Won't hold air at all, fill it up to 3000 psi, it's empty in no time. Worthless piece of junk!

Pretty much everything except the fact that I don't know how to fill it so it's just collecting dust .
