DNZ X91500 Black Aluminum 1" Tube Medium Rings
DNZ X91500 Black Aluminum 1" Tube Medium Rings are a solid choice for hunters and shooters who want a lightweight, durable scope mounting system without the weight penalty of steel. Built from billet 6061-T6 aluminum and machined as a single unit, these medium-height rings offer the strength and rigidity needed for hunting rifles and range guns while keeping your rifle nimble in the field. The ring height positions your scope centerline 1.06" above the receiver—a medium stack that clears most barrel profiles while staying low enough for natural cheek weld.
These are two-screw-per-ring standard rings, 0.63" wide, with an outside-to-outside distance of 4.820" for long-action rifles. They're designed for right-hand firearms. All fasteners—both the base screws (6-48 × 1/4") and ring screws (6-40 × 5/8")—use a 7/64" Allen wrench, so field adjustments are straightforward with a single tool. The solid aluminum design eliminates moving parts between your firearm and optic, meaning no sag, no creep, and no excuses once you've dialed them in.
DNZ rings absorb recoil shock and handle temperature swings better than steel equivalents at a fraction of the weight—ideal whether you're glassing from a ridgeline, hunting in extreme cold, or spending long days at an outdoor range. The precision socket-head cap screws provide rock-solid holding power with smooth, predictable torque feel during installation.

Yes. Both the base screws and ring screws use 7/64" Allen wrenches, so you'll only need one size hex key for any adjustments or tightening.
