I purchased my Kratos .22cal based upon your good reputation for customer service and parts availability, well those two things took a serious punch to the face lately. My power valve o-rings are leaking, from reading other posts I'm beginning to believe that it may be a common problem. That in itself isn't a big issue, the fact that you won't (yes-I said won't) sell them to me or tell me what size they are is a big issue. However your customer service rep said if I sent the rifle back to you that you would fix it under warranty. My issue with that is the down time involved with that. It would take less time to install the o-rings myself than it would take just driving to the nearest FedEx/UPS store. I also don't take kindly to your rep threatening to void my warranty over such a simple repair. If you did something to anger the factory to the point where they won't tell you the o-ring size or supply you with them, that's between you guys. We as customers who laid out serious hard earned cash for these rifles don't deserve this kind of treatment.
