Been there, done that, even with my tuned R9s……….

Recently in an attempt to reduce the stop pin hole deformation I started applying some valve grinding compound in the dovetail grooves before clamping the mounts to the receiver and this has indeed stopped scope mount creep……….

Look at this pic and you can see a bit of compound “squeeze out” at the base…………

One of the things I like about that compound is the fact that it’s “grease with grit” so the dovetail groves in the steel receiver are “rust proofed” where clamped. Before using the compound I would completely degrease the dovetails and scope mount clamps attempting to minimize slippage, however the degreased surfaces also invited rust and corrosion at the base clamp.
