RPM Precision 30mm scope rings with an integrated co-linear bubble level bring serious shooting geometry to your rifle setup. Whether you're dialing in a precision rifle for long-range hunting, running a tactical build, or setting up your go-to hunting platform, proper scope mounting starts with true alignment—and these American-made rings make sure your optic sits exactly where it needs to be. The built-in bubble level is visible from your shooting position using your non-dominant eye, letting you verify cant before and during the mounting process without juggling extra tools or eyeballing alignment the hard way.
Built from 6061-T6 aluminum bodies with 303 stainless steel cross bolts and nuts, these rings are engineered to hold tight and stay put. The medium height is sized for 30mm tube optics, and an alignment lug on the cap ensures repeatable, square cap-to-base registration during installation—no guesswork when you're torquing down. RPM machined these in the USA, and it shows in the fit and finish.
Setting up a new scope is one of those jobs where doing it once and doing it right saves hours of frustration later. The integrated level cuts out the back-and-forth of traditional mounting methods and gives you confidence that your scope's reticle will track true across your entire dial range. Torque the caps to 18 in/lbs and the cross bolts to 45 in/lbs, and you're done.

Yes, these are designed for 30mm tube optics. The medium height fits standard rifle platforms and configurations. If you're unsure about height compatibility with your specific rifle and optic, check your scope's objective bell diameter and your rifle's rail profile—we're happy to help you confirm fit.
The co-linear bubble level is visible from your shooting position when you look through your non-dominant eye. During mounting, it gives you a quick visual reference to check whether your scope is canted left or right, eliminating the need for separate leveling tools and multiple adjustments. Proper alignment improves accuracy consistency and scope tracking across the entire elevation dial.
Cap screws should be torqued to 18 in/lbs, and the cross bolts to 45 in/lbs. Using a proper torque wrench ensures even clamping pressure and prevents either over-tightening (which can damage the rings or base) or under-tightening (which risks zero shift).
Yes. RPM manufactures these rings domestically, and the aluminum bodies and stainless steel fasteners are built to hold zero and resist corrosion in the field.
