The Warne M660M is a one-piece steel tactical rail machined specifically for the Browning A-Bolt and A-Bolt II long action, in a matte black finish. Built around the Mil-Spec 1913 Picatinny rail system, it gives a strong, true platform for mounting optics and accepts either Picatinny or standard Weaver-style rings. This is the standard, zero-MOA version — flat, with no built-in elevation taper — which suits shooters who don't need extra upward adjustment range and want their scope's elevation travel centred around zero. The cross slots follow the 1913 Mil-Spec pattern for secure, repeatable ring positioning, and the rail mounts to the receiver with Torx T-15 socket-cap screws, torqued to a recommended 25 in/lb. It covers the full spread of Browning A-Bolt long-action calibres, from .223 Rem and .22-250 through to magnums such as .300 Win Mag and .375 H&H Mag. Solid steel construction gives a rigid, durable base, and the Mil-Spec rail lets the shooter fit modern Picatinny-mount optics, red dots or night-vision units in place of a traditional two-piece scope base.
