RPM Precision 30mm Low (.885'') Scope Rings with Co-linear Bubble Level
$174.99
RPM Precision 30mm low scope rings with co-linear bubble level combine solid engineering with a shooter-friendly feature that most standard rings ignore: a built-in level you can actually see without leaving your shooting position. Whether you're setting up a long-range hunting rifle, a precision target gun, or a tactical build, canting your scope—even slightly—degrades accuracy. These rings put cant verification right in front of your non-dominant eye before every shot, letting you dial in perfect alignment without juggling separate leveling tools during mount installation.
Built from 6061-T6 aluminum bodies and caps with 303 stainless steel cross bolts, RPM Precision rings are designed to hold zero and handle field use. The alignment lug ensures the cap and base stay indexed during assembly, so your mount goes together square and stays that way. Made in the USA, these are solid rings for hunters and shooters who don't settle for generic hardware.
Fit your 30mm scope tube and low-profile mounting needs with confidence. The .885-inch height is engineered for applications where clearance matters—think low-mounted optics on modern chassis rifles or compact builds. Torque specs are straightforward: 18 inch-pounds on cap screws and 45 on the cross bolt. Depending on your exact configuration, you're looking at roughly 4 to 5 ounces of ring weight.

Frequently Asked Questions
What does the co-linear bubble level do?
The built-in level is visible from your shooting position using your non-dominant eye, letting you verify scope cant before each shot without leaving your cheek weld. It also eliminates the need for multiple small tools during the initial scope mounting process, making alignment faster and more accurate.
What height scope rings are these?
These are low rings at .885 inches. Low rings are ideal for modern chassis rifles, compact builds, and setups where you need minimal clearance between your scope and receiver or action.
What torque specs should I use?
Tighten cap screws to 18 inch-pounds and the cross bolt to 45 inch-pounds. Proper torque ensures the rings hold zero without stripping fasteners or damaging components.
Are these rings only for hunting?
No. The 30mm low configuration and precision machining make these rings suitable for hunting, precision rifle competition, target shooting, and tactical applications where a low-profile, level-equipped ring adds value to your setup.
