Designed for Browning A‑Bolt WSSM rifles manufactured after 2005, these Leupold two‑piece Standard (STD) bases provide a secure mounting platform for scopes used with calibers under .300 Win. Mag. The STD system matches precisely with STD 1‑piece or 2‑piece rings and is intended to preserve your scope’s elevation travel for BDC dials when shims are fitted.
- Pivoting front dovetail ring: allows lateral adjustment using the rear windage screws while bore‑sighting, simplifying initial alignment.
- Interchangeable heights: STD rings are available in five heights to help achieve the correct line of sight with your optic and rifle action.
- Shim-ready: use shims to set correct elevation and reserve turret adjustment for ballistic compensation.
Made in the USA and built to hold up under demanding use, these bases are engineered to pair with Leupold optics and maintain a reliable link between scope and firearm.
