The Ruger 90277 3BHM scope ring delivers secure optic mounting with precision-machined aluminum construction. This low-profile ring accommodates 1-inch scope tubes while maintaining minimal height above the receiver for optimal cheek weld and sight alignment.
What Makes This Different
Unlike generic aftermarket rings, the Ruger 3BHM features integrated recoil lugs that lock directly into receiver grooves for zero movement under heavy recoil. The four-screw cap design distributes clamping force evenly around the scope tube, preventing damage to delicate optics. Each ring undergoes CNC machining to maintain consistent tolerances within 0.001 inches.
Key Features
- Precision-machined 6061-T6 aluminum construction with matte black anodized finish
- Low profile design positions scope 0.87 inches above receiver centerline
- Integrated recoil lugs prevent forward/backward movement during firing
- Four-screw ring caps distribute clamping pressure evenly
- Compatible with Ruger 10/22, American Rimfire, and other grooved receivers
- Accommodates standard 1-inch diameter scope tubes
- Torque specifications: 15-18 inch-pounds for optimal grip
Field testing demonstrates the 3BHM rings maintain zero through thousands of rounds across various calibers. The low mounting height works particularly well with standard combed stocks, eliminating the need for cheek risers or awkward head positioning. Weather resistance comes from the Type III hard anodizing that resists corrosion and wear from repeated mounting cycles.
