I got a .25 for Christmas. Haven't set it up yet, want to get a bipod stand for it first. This is my first PCP so just a little nervous, don't want to screw it up! Would like to get one for my grandson, just something we could do together. Just wonder why they would put such a small air cylinder on it in the first place, or maybe give you the option to order a bigger air supply from the on set?
