I’ve bought this used and have owned it for a number of years. It served as my main yard rifle but developed a slow leak. I took it to have it resealed but the next week it was leaking again. I tried to do it myself but was unsuccessful also. The rifle was purchased by the original owner and shipped to AZ for his shroud, trigger work, and a tune ($675 worth of work.) I purchased it shortly thereafter. It performed flawlessly for a long time until the leaking issue. It has some scratches on the outside of the valve housing but the O-ring should keep that from being an issue. If someone has one of these and wants to buy it for the top end to use the custom spacer and shroud, it would be worth it just for those or you may want to try to fix it. The barrel shoots incredibly well also. I am offering it for $425 shipped within the Continental U.S. which includes only the rifle and one magazine.
