I purchased this pump to recharge my PCP air rifle. I wanted to see if a pump at this price point was any good. Well I can definitely state that in terms of value for money it represents awesome value. My air rifle requires topping up to 200 bar, which after firing around 50 pellets takes between 40 to 50 pumps and if I fire around 100 pellets, it requires around 80 to 95 pumps. I wouldn't say it is overly difficult to do it just takes a little time and effort to do it, and also the right technique. I would recommend this pump for PCP air rifles, so long as you realise that you will need to put a little effort in each time you use it. Look on the bright side it is great exercise!
