I just installed a 3-9 Nikon Prostaff EFR on my Brothers Crossman Quest 1000x Break barrel .177 caliber.Initially the POI was very low. I had to use nearly all of the elevation adjustment on the scope (I know it is not good to do that) and the rifle was still shooting 6-7 inches low at 20 Yards. I guess I have some Barrel Droop. I cut up an Aluminum soda can and made a shim for the rear scope mount. Two layers of aluminum equal about .008 in. That .008 inch shim got me to within about 3 to 3 1/2 inch of Point of aim. Still Low and still using most of the scopes Elevation adjustment. I am reluctant to make the shim too thick, because I dont want to damage the scope tube. Also, I know I need to back off on the Scope Elevation adjustment so as not to stress the erector tube spring. That means an even thicker shim which may not be a good idea. I'm sure this subject has been covered in the Forum and I DID do a search, but I didn't find anything about shims. Could be my search skills not so good, Lol.I would appreciate any wisdom regarding this problem, or maybe a link to a previous discussion of the topic.
If the gun is still within warranty exchange it. That is FAR too much droop.

Decades ago I messed with a couple brands of adjustable mounts and found that it was too much of a hassle spending a couple hours setting up, only to have the setting "shake loose" during the season. here's my "barrel tweaker"..........Takes a bit of "fiddlin' around" but once set there isn't any "shootin' loose".
Well,,,, I've looked at this from a couple different directions now.I can go with Droop Compensated scope mount/fixture,,, but that will cost me at least $70, maybe more in the end. Thats too much $$,,, as this gun is worth less than $100.Now I'm looking at bending the Barrel. At first, I thought that was a bit extreme, maybe even a little crazy, Lol.However, after doing some research, its looking to be totally viable and fairly easy to accomplish. Its certainly cheaper!I"m gonna give it a go and see what happens. I'll be sure to post my results when I'm done.
Before bending your barrel on a new gun under warranty try a different scope and rings. Just my 2 cents
By chance do the mounts have a built in drop compensation?
