Stopped by Big 5 today and picked up a Remington Summit is .177 caliber. I talked the clerk over the phone and he told me the gun was their display model and had no box or paperwork, because of this he knocked the price down to $130. I asked him to set it aside and I would come take a look at. When I arrived and asked to see the gun I noticed 2 fairly significant chips in the high glass lacquer finish, not wood damage under the chips. Based on the dings in the stock he said he would let the gun go for $100 bucks. Based on the fact that it had a nice clear Crossman 3x9AO scope on it I thought the price was reasonable. The clerk said he was unsure as to the guns history, didn’t know if it was previously purchased and brought back or what. He said if I was unsatisfied I could return the gun. While walking out of the store to my truck I noticed that something on the gun was terribly loose. When I got in the truck and looked the gun over I noticed that the one piece scope mount was loose on the dovetails, loose the point of sliding quite freely. I brought the gun home and tightened everything up and went to basement to shoot it. The first couple of shots had the sharp crack of new gun, so I don’t believe it was shot before this occasion. After a few shots the loud crack was gone but now I had noticed something new. The cocking stroke is smooth and the firing cycle isn’t harsh at all. But upon closing the barrel it doesn’t lock up extremely positive. Meaning that it will open slightly and stay that way prior to completely unlocking. I even tested to see if the gun would fire with the barrel somewhat opened sure enough it did. Now I understand that the gun won’t find it’s true accuracy for quite sometime. But I’m less then pleased with the way the barrel lock up, or lack there of, feels. It was the only gun that Big 5 had and I would really like to have this gun in my arsenal. Should I contact Crossman and see what they are willing to do for me or should I just return it and get my money back? Can this problem be fixed without sending it back to Crossman? I believe that I have read here that some of you guys out there have this gun or at least what ever the gun is cloned after. How do yours feel when locking up? Any feedback would be gratefully appreciated.
