Talley Manufacturing Picatinny Base Features The Talley Manufacturing Picatinny Base is machined entirely from high grade 7000 series aluminum alloy giving it a lightweight yet rugged construction suited to hard use in the field. A hard-coat anodizing process takes the finish to 65 Rockwell hardness protecting the base from scratches and wear over the lifetime of the firearm it is mounted to. Designed and manufactured in accordance with MIL-STD-1913 Picatinny rail specifications this base provides a reliable mounting platform compatible with any optics mount built to that same standard including Talley s own line of Picatinny scope mounts. The 20 MOA cant built into the base shifts the mounting angle to help a compatible scope use more of its internal elevation adjustment range which is particularly useful for long range shooting. Fully CNC machined to the industry s tightest manufacturing tolerances this single-piece base is designed to fit the Winchester Xpert 22 with precision ensuring a secure repeatable mount for optics. Being made in America it reflects the same quality control and attention to detail found across Talley s full line of scope mounting products. The package includes mounting screws specifically 1/4 inch 6-48 screws along with a T-15 wrench so installation can be completed without searching for separate hardware. For Winchester Xpert 22 owners looking to add a dependable optics mounting platform this anodized red base delivers precision fit and long range capability in one straightforward upgrade.
