30mm Medium Dovetail Scope Rings

This pair of Sun Optics scope rings fits 30mm tube scopes onto .22 or 11mm grooved receivers. The medium height suits rifles where the objective bell clears the barrel with standard clearance. Hunters and target shooters seeking a straightforward steel mounting solution for rimfire or air rifles will find the specification matches that need.

Installation and common issues

The rings clamp to the dovetail rail using a steel recoil key and two Torx-head cap screws per ring, so only a Torx driver is required. No gunsmithing is needed, but the thin-line caps demand even torque on both screws to avoid canting the scope tube. Stripping is reduced by the Torx heads, yet over-tightening can still damage the dovetail grooves on softer alloy receivers.

Dovetail interface limits

The .22 and 11mm dovetail standard relies on friction and the recoil key for shear resistance, so heavy-recoil centre-fire calibres can shift the rings over time. The two-screw caps hold the scope tube but do not offer the clamping force of a four-screw Picatinny ring set. Vertical adjustment is fixed by the medium ring height, so scopes with very large objective lenses may require a different ring height not provided here.

Questions about this item

How do I verify the rings hold zero on my .22 dovetail rail after installation?

Torque the Torx head cap screws evenly, confirm the steel recoil key seats fully in the 11mm groove, then fire a test group to check point-of-impact consistency.

What comes in the SM234 package and what must I supply?

The pair includes two 30mm steel rings with two-screw caps, Torx screws and integrated recoil keys; you supply the scope and a Torx driver.

Which ring height suits a 30mm tube on a standard .22 receiver?

The medium height in this SM234 pair positions a 30mm tube at the correct optical centreline for typical .22/11mm dovetail rails.
