The Leupold STD two-piece bases for Browning A-Bolt rifles chambered in WSSM cartridges (part no. 57340) give that specific short-magnum action a stable, rotary-dovetail mounting platform built to handle the added recoil of the WSSM family. Leupold machines the bases from steel and finishes them in matte black, and the rear ring’s windage adjustment lets a shooter correct lateral alignment without touching the scope’s own internal windage. The two-piece configuration allows independent front and rear mounting for solid alignment. Among WSSM-specific scope bases, this STD configuration is machined for that exact chambering’s A-Bolt receiver.
