Leupold Ring Mount Fits Ruger M77 30mm High Matte Finish 51042 UPC 030317510428
Product Description
The Leupold Ring Mount set for Ruger M77 (51042) in 30mm High is a premium steel optics mounting solution designed to attach 30mm maintube riflescopes directly to the proprietary mounting dovetails machined into Ruger receiver bridges. Engineered as a seamless, rock-solid alternative to factory rings, these High-profile scope rings provide precision alignment and rugged holding power for big-game hunting rifles and target setups.
Precision-machined from solid steel, Leupold Ring Mounts are designed to interface directly with Ruger’s integral receiver cutouts without requiring secondary adapter bases or Picatinny rails. Because Ruger M77 and Hawkeye actions feature offset receiver heights between the front and rear bridges, this ring set includes correctly offset ring heights to establish a perfectly level optical axis above the bore line.
Finished in a durable, non-reflective Matte Black coating, the 51042 ring set features integrated recoil lugs that lock tightly into Ruger's receiver notches, absorbing severe recoil energy from heavy magnum calibers. Equipped with grade-8 hardware, Leupold Ring Mounts provide marksmen with a sleek, low-profile interface that guarantees zero hold through hard field use and extreme environmental exposure.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Fits Ruger rifle receivers with integral scalloped bases (Ruger M77, M77 Mark II, Hawkeye, and Super Redhawk). High ring height accommodates 30mm maintube scopes with objective lenses up to 50mm–56mm outer diameter.
- Ensure the host firearm is completely clear, magazine floorplate open, and chamber visually and physically verified empty.
- Clean and degrease the Ruger receiver dovetail cuts and ring clamping bases using isopropyl alcohol.
- Mount the taller ring onto the rear receiver bridge slot and the shorter ring onto the front slot, ensuring the integrated recoil lugs seat completely into the receiver notches.
- Place the scope into the bottom ring halves, loosely install top caps, verify reticle alignment and eye relief, then incrementally torque ring screws to 28–30 in-lbs using a cross-pattern sequence.
