I recently saw your youtube video on the airgun advancement channel I think. Idk I watch alot. Anyway I heard Umarex themselves say they have a confirmed output pressure of 1950 psi. So I have a umarex fusion which you may already know is a qb79. I have plans on going hpa but 1950 is generally reguarded as dangerous. I know Umarex will not sell us something dangerous so I have to know either what was done to beef up the gun or if weve all just been weanies and over cautious? I suspect that they put strong scews in the tube and more than 2 of them but in any case I cant wait for the 25 guantlet but Im still saving for the hammer so maybe next year ?
