Tapco TAP22044 Scope Base Ruger 10/22 20 MOA Picatinny Rail

The Tapco TAP22044 scope base transforms the Ruger 10/22's limited mounting options into a versatile Picatinny rail platform with built-in 20 MOA cant. This precision-machined aluminum base eliminates the guesswork in long-range shooting by providing the elevation advantage needed for extended distances.

What Makes This Different

Unlike standard zero-cant bases, the TAP22044 incorporates a 20 MOA downward slope that maximizes scope adjustment range for long-distance shooting. The one-piece design replaces factory grooves with a full-length Picatinny rail, providing multiple mounting positions and rock-solid scope retention. CNC-machined from aircraft-grade aluminum, this base maintains zero through thousands of rounds while weighing just 2.1 ounces.

Key Features

• 20 MOA built-in cant extends effective range beyond 300 yards
• Full-length Picatinny rail accepts any MIL-STD-1913 compatible rings
• CNC-machined 6061-T6 aluminum construction for dimensional stability
• Direct replacement for factory Ruger 10/22 receiver grooves
• Matte black hard-anodized finish resists corrosion and wear
• Precision-drilled mounting holes ensure perfect receiver alignment
• Low-profile design maintains classic 10/22 aesthetics

The 20 MOA cant proves invaluable for precision rimfire competitions and varmint hunting where shots extend beyond 200 yards. Competitive shooters gain additional elevation adjustment without maxing out scope turrets, while hunters benefit from flatter trajectories on prairie dogs and ground squirrels. The hard-anodized finish withstands field conditions and maintains its appearance through seasons of use.
