Talley Manufacturing Picatinny Base Features The Talley Picatinny Base is fully CNC machined from lightweight 7000 series aluminum alloy giving it the strength to handle recoil over the lifetime of the firearm without adding unnecessary weight. A hard coat anodizing to 65 Rockwell protects the base from wear and corrosion in field conditions. Designed in accordance with MIL-STD-1913 Picatinny rail specifications the base accepts any optics mount built to that same standard including Talley s own line of Picatinny scope mounts. This precision manufacturing ensures the base mounts securely and holds zero under repeated use. Built specifically to fit Browning BLR rifles the base is designed and manufactured with the industry s tightest tolerances for a precise factory-like fit. It ships complete with mounting screws and a wrench specifically 1/4 6-48 screws and a T-15 driver so everything needed for installation is in the box. Because some BLR rifles use the BAR mount pattern instead shooters should verify screw hole spacing before installing. Made entirely in the USA the Talley Picatinny Base for Browning BLR gives hunters a dependable optics mounting solution available for sale at GrabAGun.
