I noticed threadlok on the stock screws but a few told me they saw that on some new guns so i tossed that aside. Today i went to install my new scope and saw a piece of black sticky rubber on the rear scope mount placed there as a shim. This the factory doesnt do!! I got shafted.
-
the tape that helps hold the scope in place and not scratch the finish?
-
This local gun shop has all of the air guns out of the box and some had the scopes allready installed. This was clearly a shim. Somebody bought it and probably returned it. I might try and see if it was registered. A bought and returned gun is not something i want. Some idiot could have dry fired the thing 50 times for all i know.

My Whisper came with blue thread locker on the stock screws and an extra thick piece of tape in the bottom of rear of the scope mount. I'm, told it's there to tip the scope down a bit to help get the scope to have a more centered retical for the shorter ranges of airguns, and deal with the slight barrel droup some break barrels have.
Blue thread locker on the stock screws and an extra layer of tape in the scope mounts doesn't nessisarily mean the gun was used.

Was the tape inside the rear ring or under it? I've had rings come with the crap stuck inside of them, like it or not.
-
A few of my "Package" scope/scope mount came with abit of tape stuck onto one and sometimes both of the bottom of the scope rings. The tape might be used to give the rings a better grip on the scope.
-
They put that sticky tape there because the recoils from the rifle tends to shift the scope. And you're not supposed to tighten down the scope more than 15 in. lbs. lest you bend the scope tube. Not only that, but the place you bought the rifle from may have sighted it in for you before they shipped it. Threadlock on the screws is standard. All the Gamo guns I bought have it on the screws.
-
100% correct. That black tape came with my package scope on my Hunter Sport. Reinstalled the Scope WITH the tape in place. 700 rounds and counting my scope and gun are working seamlessly. Tape is definitely from the factory.

Again, this is INSIDE the rings? A shim would be under the mount and on top of the rail. Tape makes a lousy shim, BTW.
-
It lays in the grove of the rear ring, the scope would rest on it.

Mine had the extra layer of tape under the scope, not the mount.
BTW, the best way to shim with dovetail type mounts is under the scope, not the dovetail. Reason being, under the scope the mount stays centered. If you shim under one end only of the mount's dovetails, because they are roughly at a 45 degree angle the mount will cant sideways just as much as it gets raised by the shims. And, as shim thickness increases, the shimmed mount has less gripping surface area therefore, doesn't have as strong a grip and can even dent/distort aluminum dovetails.
For shimming scopes I use the electrical "friction tape" available at hardware stores. It's very much like the cushioning tape that originally comes in the mounts, only a bit thicker. It shims and cushions at the same time. And with that type tape being sticky on both sides, the mounts don't have to be tightened close to the point of denting the scope tube to hold the scope in place. I've used it for all my scope mounting, even on slug firing shotguns which have way more recoil than any springer, and the scopes don't move in hot or cold weather.

I got a Whisper Deluxe and the bottom back ring had this tape on it. it had about 5 layers of it as opposed to one on the front bottom ring. My bet is that it is being used as a shim to compensate for a bit of barrel droop??? Just a thought. this is definitely from the factory though

Mine came out of the box with tape on the scope mount.
