Yes, I must agree. The Bushnell 3-7 mount slides onto the rifle rail and the scope does the same on top of the mount. I am always having to re-zero. With my laser bore-sighter in the muzzle I will look through the scope at a wall and see the red dot. Then I flex the fore-stock and can see the red dot move quite a distance.
When standing at thirty to fifty yards I hold the rifle very lightly and everything works out well. If I rest the rifle I place it so only the area in front of the trigger guard (I have a 66) contacts the rest. Again this causes no flex.
Having said all that it is a fabulous rifle. Nothing was done to or replaced on the rifle yet it never had any problems with stoppages the way my 10/22 did until I bought an aftermarket extractor for it.
I may just take the scope off as the sights are not bad at all.
