Warne 731M Rimfire 70/30 Horizontal Split Black Steel 30mm Tube Medium 3/8"/11mm Dovetail

The Warne 731M rimfire scope rings deliver solid, no-nonsense mounting for your .22, air rifle, or other rimfire on a budget without compromise. Built from steel and designed around the dual-dovetail standard found on most rimfire rifles—fitting both 3/8" and 11mm dovetails—these medium-height rings accept 30mm scope tubes and won't let you down whether you're punching paper at the range or hunting small game in the field.

What sets these rings apart is their 70/30 horizontal split design. That offset split gives you a wider clamping surface on the bottom of the scope tube while the upper portion stays thinner, creating a mechanical advantage that locks your optic in place without requiring crushing torque. For a rimfire setup, that means confidence that your sight picture stays put through the shooting session. The black steel construction is straightforward and durable—no fancy coatings or unnecessary weight, just functional strength.

Warne's reputation in the optics world comes from making quality rings here in the U.S., and these rimfire rings carry that same build philosophy. They're not over-engineered; they're built right for the job. If you're mounting a scope or red dot on a rimfire rifle and want mounting hardware that won't be the weak link in your setup, these deliver the practical strength and compatibility you need.

Frequently Asked Questions

Will these rings fit my rimfire rifle?

The 731M is built for dual-dovetail compatibility, fitting both 3/8" and 11mm dovetails. Most rimfire rifles use one of these two standards, so compatibility is likely—just confirm your rifle's dovetail size before ordering.

What size scope tube do these rings hold?

These are 30mm rings. They're designed for 30mm scope tubes, which are the most common diameter for rimfire optics.

Why is the 70/30 split design important?

The 70/30 horizontal split places more clamping surface on the bottom half of the scope tube, creating better grip without requiring excessive tightening force. That means your scope stays secure without risk of overtightening and damaging it—a practical advantage on lighter rimfire setups.
