oh . my mistake . I ' m from Alberta so it ' s only 5 % tax for me . I should Edit this in . My bad . <| sep |> Scuba tank is one , have it refilled at a diving or airgun shop . Another option is a high pressure hand pump like the one Beeman makes , would take you about a thousand strokes or so to get the gun ' s tank partially full . Another option is a socall shoebox pump or air booster . Basically , its a high pressure air pump that runs on air from your common shop compressor at 120 psi . The shoebox pump takes your existing 120 psi air supply , uses it to power a large piston which in turn drives a smaller piston pump that can reach the 3000 or 4500 psi needed for your PCP tank . <| sep |> Of course bad results for those people willing to have a heart attack for their lifestyle . But is she hurting anyone else ? Not really .
