Dan,
No warranty is what UMAREX e-mailed me.
It's like buying a pretty Chinese rifle that'll be real nice once I take apart... I bought cheap and screwed my own self in the process. Noone to blame but myself.
Far as the "Fix" goes, I'm sure a JM kit will do it and probablly greatly improve an already nice rifle. In the beginning power and accuracy were excellent. Something failed at about shot 600. I doubt I'll ever buy another similarily discounted gun. I'm getting old and too lazy to work on my guns, I just want to shoot.
Remember, that the large "R" stamped several places on the metal and wood really detracts from the appearance and will surely destroy any resale value but if you purchased the gun as just a "shooter" as I did won't mind them much. The reduced cost gets quickily offset by those stamps! I'm sure it is a legal protection that the company must take and it WILL prevent fradulant sfuture sales.
