Leupold Rifleman Features The Leupold Rifleman Gen2 base is engineered as a direct fit for the Ruger 10/22 s factory receiver meaning it bolts on using the rifle s existing mounting holes without requiring any drilling tapping or permanent modification to the firearm. Its one-piece construction provides a single rigid mounting platform rather than two separate bases reducing the number of components that need to align perfectly for a scope to hold zero over time. This design approach simplifies installation for Ruger 10/22 owners who want to add a scope without the added complexity or potential misalignment of a multi-piece base system. Leupold s Gen2 line carries the brand s long standing reputation for dependable precision optics mounting hardware into the rimfire market. The base s black finish matches the finish typical of Ruger 10/22 receivers and most riflescopes keeping the completed setup visually consistent. Because this base is matched specifically to the Ruger 10/22 platform owners avoid the fitment guesswork that comes with a universal base design intended to work across multiple rifle patterns. This straightforward purpose-built base gives 10/22 owners a reliable foundation to build out a complete optics setup with their choice of Gen2 rings.
