RPM Precision 34mm Medium (1.00'') Scope Rings with Co-Linear Bubble Level
RPM Precision 34mm medium scope rings with co-linear bubble level give you a tool that does double duty: secure your optic and dial in zero cant at the same time. Built around a 1.00" tube diameter, these rings simplify one of the most critical steps in rifle setup—getting your scope level and square to the bore. Whether you're a precision shooter dialing in at the range or a hunter preparing a rifle for field use, built-in leveling eliminates the frustration of balancing multiple tools during mounting.
The integrated co-linear bubble level is positioned so you can see it from your shooting position using your non-dominant eye. That means you can check cant before every shot without breaking your grip or dismounting. It's a small feature that catches careless angle mistakes that would otherwise tank your accuracy downrange. The level also proves invaluable during the mounting process itself—you can reference cant directly on the rings as you tighten, cutting setup time and ensuring your caps and base stay aligned without the usual juggling act.
These rings are machined from 6061-T6 aluminum with 303 stainless steel cross bolts (½") and nuts. An alignment lug keeps the cap seated properly on the base during installation, so you're not fighting geometry while you work. Recommended torque specs are 18 in/lbs for cap screws and 45 in/lbs for the cross bolt—follow those and you'll have a solid, repeatable mount. Made in the USA, the medium height rings tip the scales at 4.4 oz, balancing minimal weight penalty with real functional advantage.
