I have a Beeman HW 97 K, laminated blue stock now( that I would be selling) , but have been thinking about an FX Crown, blue laminated stock. I don’t use it ( them) very often at all and I want something very dependable , which my 97 has been. I am afraid if I buy a pcp I will have air leaks and such and maintenance will be a lot higher. I am not sure how hard they are to replace ( o rings) if it’s something I could do or would I have to have it sent out ? I would not be fiddling with it much, how ever it comes is how I will be shooting it. Maxed out on the two dials, I believe. And am happy shooting what ever pellet is recommended. So is it ok to leave them aired up for long periods of time between use ? And are leaks or any other problems ( and what kind of problems might I have ) a real concern with the crown. I would be getting it in .25 caliber as I have a coon problem from time to time and the springer ( .177 cal.) just can’t get it done. Hence the reason for wanting a new rifle. Thanks , newbie here to this sight and to this higher powered air gun stuff. Thanks in advance for any help you can offer.
