Things I liked: Pumping this tank up with a hill pump is not bad at all. Beats pumping my discovery at the range. It is light enough to carry in a backpack while hunting. This tank makes shooting much more enjoyable! I pump it while watching television, it takes about 320 pumps from 2k to 3k psi. So in about 3 hours you have it charged enough to fill your discovery 8 times. The reason I wrote this review was to offer information I attempted to find online that was not available! Pumping the first time from 0 to 3k was a job, maintaining isn't bad at all. If you use the benjamin pump it takes much longer to pump, it took me a week to pump from 0 to 3k with that pump. And 4 evenings to maintain. The hill pump is way faster.

Things I would have changed: Nothing, unless they sold a version that pumped itself while I shot!

What others should know: If you own a discovery you should definitely invest in this tank and a hill pump. If you don't shoot much, you will not benefit from it. If you shoot a lot, and hunt this tank is a must have. Even if you use a scuba tank to fill your guns, this tank is much more convenient to carry.

Things I liked: This is a replacement tank for me, now I have a spare tank.

Things I would have changed: Nothing. It does what it's designed to do.

What others should know: Mine was dated June 2013,so I have 4.5 years before I need to Hydro it. I purchased it in November of 2013.

Things I liked: It does exactly what we needed it to do, which is fill the disco 22, and not worry about the kids overfilling. I waited for a sale that allowed for the combining purchases to get free shipping

Things I would have changed: Nothing

What others should know: The bottle will not become obsolete in 15 to 20 years like carbon fiber tanks.

  • Brent from USA asked:

    So could I buy this with the Benjamin Discovery .177 and would it fit automatically or would I need to buy any other parts to make it attach to the Benjamin Discovery .177?

    • Tyler from USA:

      You would still need the fill assembly.

  • Jordan from USA asked:

    Is it possible to use this tank with the Airforce CO2 adapter on my Airforce Condor and Talon?
