Tapco Scope Base Features The Tapco Scope Base is built with 20 MOA of built in elevation to help shooters make full use of their riflescope s adjustment range when shooting at extended distances. Because the base is designed specifically to fit the Ruger 10/22 receiver installation is straightforward and does not require any fitting or modification to the rifle. A durable black finish resists wear and matches the typical finish found on most 10/22 rifles keeping the overall look consistent. Mounting screws are included so the base arrives ready to install without a trip to the hardware store for additional fasteners. Upgrading a stock Ruger 10/22 mounting system to this 20 MOA base is a practical step for shooters chasing more precision out of their rimfire rifle at range. The added elevation built into the base effectively extends how far a scope can be dialed before running out of internal adjustment which matters for shooters stretching their 10/22 beyond typical plinking distances. Because the base ships with hardware included the upgrade can be completed in minutes with simple hand tools.
