daystate wolverine with the hi-lite bottle and this is from some one with a wrecked shoulder and back. Three ops on the left shoulder so being a right handed shooter is a pain quite literally and steroid injections in the spine. So if the weight restriction is the issue then i would certainly know. Mine is 40ftlb and get about 70 shots from a fill of 210 bar. Oh! and stupid accurate, i know this as i have the video to show the range at 60 mtrs and the shots on target.
