I recently purchased a pre 64 Model 70 Alaskan in .338WM. The rifle has a factory fitted solid red rubber buttplate. I am concerned that in long term storage in my gun safe that the buttplate with be damaged if the rifle is left resting on the buttplate. Is this a valid concern and should I find a way to store the gun without putting its weight on the buttplate while the gun is is resting vertically on a solid surface.
