Keep your rings clean. Remove any burrs on the edges. I recommend lapping the rings unless you know the base and rings are well made (fully machined rings, not extruded) and the base is properly installed. Then tighten the ring screws to the proper torque value.
HighPowerOptics provides in our installation kits a very thin, yet incredibly strong
RingTrue Tape that is applied to the rings after lapping. I developed the tape for mounting scopes on .338 magnum and 50 BMG rifles. I change scopes on ballistic test rifles frequently and wanted to prevent scope slipping and the associated ring marks. It works extremely well.
RingTrue Tape is only 0.0025" thick and is resistant to heat, moisture and ultraviolet light.
While I don't always use it, I've found that in most cases it helps - and never hurts. It protects the rings from corrosion after lapping. I've found that some scope and ring anodize coatings are slippery.
RingTrue Tape improves grip and prevents the scope from slipping. It prevents ring marks of any kind. I also use it on some tactical rings instead of lapping them.
