DNZ X97500 Black Aluminum 30mm Tube Medium Rings
The DNZ X97500 Black Aluminum 30mm Tube Medium Rings are a lightweight, precision-machined mounting solution for long-action rifles where you need a solid, no-nonsense connection between your receiver and scope. Built from billet 6061-T6 aluminum and machined as a solid block, these rings eliminate the flex and play that separate components can introduce—there's nothing but metal and threads between your firearm and optic. If you're setting up a hunting rifle, tactical build, or long-range shooter and want maximum rigidity without carrying steel weight, this is the kind of foundation that matters.
What makes aluminum rings a smart choice is their weight savings—DNZ's billet construction delivers roughly 67% less mass than comparable steel one-piece mounts—while maintaining serious clamping strength through precision socket-head cap screws and dense machined geometry. Aluminum also handles temperature swings and recoil shock as well as steel does, so you're not sacrificing durability for the lighter carry. These rings sit at a medium height, positioning your 30mm tube 1.19" above the receiver centerline, which suits most standard rifle setups and optic mounting preferences.
Installation is straightforward with a 7/64 Allen wrench for both base and ring screws. The two-screw-per-ring design keeps things simple and proven, while the 4.820" outside-to-outside spread fits long-action platforms. Hole spacing is engineered for solid bedding on standard long-action receivers, so you're not working around quirky geometry.

Frequently Asked Questions
Will these rings fit my long-action rifle?
Yes—the DNZ X97500 is designed for long-action firearms with right-hand ejection. The 4.820" outside ring dimension and hole spacing (0.70", 3.931", 0.70") are engineered to match standard long-action receiver geometry. Verify your rifle's action length before ordering.
What size scope tube do these rings accept?
These are 30mm tube rings. Your scope's main tube must measure 30mm in diameter to fit securely.
How much higher will my scope sit with medium rings?
Medium rings place the scope's centerline 1.19" above the receiver's top surface. This is a standard height that works well with most hunting scopes and optic packages on long-action rifles.
What tools do I need to install these rings?
You'll need a 7/64" Allen wrench to tighten both the base screws (6-48 X 1/4") and ring screws (6-40 X 5/8"). Proper torque to spec ensures a rock-solid mount without over-tightening.
