The EGW Browning AB3 Long Action Picatinny Scope Base (brand part number 43400) mounts a Picatinny-pattern rail directly to a Browning AB3 Long Action receiver, built to a 0 MOA incline. Evolution Gun Works machines the base from 6061-T6 extruded aluminum and finishes it in matte black for a durable, corrosion-resistant mount. The base ships with hex-head screws and a wrench for installation, and EGW recommends 20 inch-lbs of torque with a drip of blue Loctite on the screws. It’s made in the USA to EGW’s standard tolerances.
