The EGW Browning A-Bolt WSSM scope base delivers precision and flexibility for shooters who want to upgrade their Browning A-Bolt rifle without gunsmithing. This one-piece Picatinny rail mounts directly to your factory receiver holes—no drilling, no tapping—and gives you the freedom to adjust eye relief quickly or swap scope rings without permanent modifications. Whether you're setting up a hunting rifle or a range gun, this mount lets you dial in the perfect sight picture and experiment with different optics.
Built from 6061-T6 extruded aluminum, the base is rigid and lightweight, with a milled center channel that keeps weight minimal without compromising strength. The full-width Picatinny slots are gauged to military spec (MIL-STD 1913) with precision tolerances of ±0.002 inches—tight enough to work flawlessly with both Picatinny and Weaver rings. Socket head Torx screws and a wrench come in the box, so you're ready to mount out of the gate. EGW recommends 20 inch-pounds of torque and a drop of blue Loctite to lock everything down securely.
If you're running an A-Bolt WSSM and tired of factory rails or want the reliability of a one-piece design, this base is a straightforward, shop-friendly solution. It ships complete and ready to use.
