[Duncans ProView] 30mm Med Dovetail Scope Mounts 11mm (x2)

These are a pair of good quality medium-profile scope rings (or mounts) made by ProView designed to securely attach a rifle scope with a 30mm main tube diameter to an airgun or firearm equipped with a standard 11mm dovetail

The "Med 30mm Tube" part refers to the rings being sized for modern rifle scopes with a 30mm (about 1.18") main tube.

"Picatinny/Weaver" means they clamp onto the slotted rail system found on most tactical rifles, ARs, and many hunting or air rifles. The "11mm" designation is common terminology (especially in UK/European markets and airgun communities) for the standard Dovetail rail width/profile, distinguishing it from wider 20mm picatinny/weaver rails.

Features and Specs

These mounts are sold as a pair (two rings)

Construction: CNC-machined from lightweight, strong aircraft-grade aluminum (e.g., 6061-T6 alloy) with a matte black anodized finish for durability and reduced glare.

Height/Profile: "Medium" profile raises the scope's center line higher above the rail (often ~29mm / ~1.14" or more from rail top to tube center). This provides extra clearance for large-objective scopes (50mm+), barrel contours, or iron sights, and is popular on flat-top ARs or rifles needing higher eye relief.

Mounting: double screw clamp-on design with hex/Torx screws, includs sa recoil lug or stop to resist shifting under fire.

Extras: Includes protective inserts/tape inside the rings to prevent marring the scope tube, plus tools for installation.

They are precision-machined for a solid hold- Common Uses -Mounting rifle scopes on AR-15s/MSRs, bolt-action rifles, shotguns, or air rifles that have a Picatinny/Weaver rail.

Ideal for hunters, target shooters, or tactical users who need reliable, repeatable optics mounting without permanent modifications to the firearm.

Medium profile is especially useful when your scope has a large bell or when the rifle's rail sits high relative to the bore.

Pros and Cons

Pros: Lightweight, easy to install/remove, affordable, widely available, and sufficient for most non-extreme-recoil applications.

Cons: Lower-end versions may not hold zero as consistently under heavy magnum recoil compared to premium brands (e.g., Burris, Warne, or Vortex). Always use proper torque specs and thread locker.
