My CFX seemed to be having some excessive velocity variation, short story is I determined it was the front rotary breach seal. Now if you check Gamo USA's site, the list 3 different seals in 4 packs, that cover every rifle they make...except the CFX. Now I've heard that Gamo's parts support is non existant, and that these seals just aren't available, but since I had some time to burn, I decided to actually call them. Surprisingly enough, I got through to a real person in a matter of minutes. When I told him what I was looking for, his initial response was that they weren't available. When I asked why, he said they don't supply them because you have to dismantle the rifle to replace the seal. Which means you void the warranty. Well, you don't have to take the rifle apart to replace the front seal, and I made it clear I knew that. Then he said I could send it in for warranty service, I told him I'd already voided the warranty, so now what do I do? He asked for my name and number, and promised to call back within 15 minutes. Yeah, right. In fact, it was 10 minutes, and I have 4 seals on the way at the same price as the other seals on the site. Don't know the part number yet, but will post if anyone is interested once they get here. So maybe things are looking up in Gamo Cust. Svc. Try to talk to a guy named Kyle, and good luck.
