Thanks Chasdicapau. That definitely makes it more affordable. I'm filling my tanks only."chasdicapua"Terry, If you're filling up a carbon fiber tank from the Nitrogen tank, you don't need the regulated set up and can save $300. But if you're going to fill your rifle directly from it, the regulated set up would be safer.
Thanks Goodtogo. I've got a corner of the garage picked out that should work fine. Out to the barn to find a couple 2 bys."Goodtogo"If you do go with N2, a simple fix to make the tank safe in your garage is screw a couple of horizontal 2x4s to the wall and use two ratchet straps screwed to those to fix it too the wall.
