Warne 45 Degree Picatinny Side Mount Adapter Dark Earth

The Warne 45 Degree Picatinny Side Mount Adapter in Dark Earth is a no-nonsense offset rail solution for flat-top MSRs and other tactical rifles. Built from machined aluminum, this side-mounted adapter bolts directly to any Picatinny rail—upper receiver, handguard, or anywhere else you have picatinny real estate—and gives you a 45-degree angled platform for lights, lasers, backup sights, and other accessories. The offset angle keeps your primary optic's sight picture completely clear while positioning secondary gear exactly where you need it.

Installation is straightforward: no gunsmithing required, no drilling, no permanent modification to your rifle. The Dark Earth finish matches modern tactical gear and blends into most modern rifle platforms. Warne designed this mount with an eye toward weight consciousness—the aluminum body features cutout sections that shave ounces without compromising strength. The side rails have been updated with four cross slots total, giving you multiple mounting positions so you can fine-tune accessory placement to your setup.

Whether you're running a backup BUIS that needs to co-witness with a primary scope, mounting a weapon light off to the side, or securing a tactical sling attachment, the 45-degree offset angle is a time-tested formula in modern rifle builds. Warne's version keeps things simple and repeatable—exactly what you want from a mounting interface that will hold your gear rock solid downrange.
