Talley Manufacturing Picatinny Rail Features The Talley Manufacturing Picatinny Rail is fully CNC machined from 7000 series aluminum alloy a lightweight yet strong material choice that keeps the rail s added weight minimal on a rimfire rifle. A 20 MOA cant is built into the rail s design shifting the scope s elevation adjustment range toward compensating for bullet drop which extends the practical range at which a Bergara BMR can be shot accurately before exhausting the scope s internal elevation travel. The rail is designed and manufactured to the industry s tightest tolerances ensuring it fits the Bergara BMR s receiver precisely without gaps or movement. Hard-coat anodizing to 65 Rockwell protects the aluminum surface from wear and corrosion through repeated optic changes over the rifle s service life. Built in accordance with MIL-STD-1913 Picatinny rail specifications this base accepts any properly designed Picatinny scope mount including the full line of Talley Picatinny scope mounts. The one-piece rail design provides a single rigid mounting surface rather than separate bases reducing the chance of misalignment between mounting points. Mounting screws and a wrench are included specifically 1/4 inch 6-48 screws requiring a T-15 driver making installation straightforward without needing to source separate hardware. Made in America and weighing just 1.7 oz the Talley Manufacturing Picatinny Rail gives Bergara BMR owners a precision American-made upgrade for mounting their optic of choice.
