Warne Scope Mounts A645 45 Degree Picatinny Side Mount Adapter - Dark Earth

The Warne A645 Picatinny Side Mount Adapter is a 45-degree offset rail built to provide an angled mounting platform for secondary optics, red dots, reflex sights, or backup sighting systems on a tactical rifle. Designed specifically for Flat Top MSRs (such as the AR-15) and other tactical-style firearms, the A645 clamps onto any standard Picatinny rail and creates an additional accessory slot rotated 45 degrees off the primary optic's line of sight, letting the shooter quickly transition between a magnified primary and a non-magnified close-range sight.

Machined from lightweight aluminum, the A645 keeps added weight to a minimum at the rail while delivering the rigid, return-to-zero hold shooters expect from Warne. This variant is finished in Dark Earth (FDE) for color coordination with flat-top AR uppers and handguards in matching earth-tone builds.

Installation is straightforward: the adapter clamps to an existing Picatinny rail section with the included hardware, putting the offset accessory platform at a natural 45-degree angle that is easily accessed by canting the rifle slightly. Whether running a primary LPVO or fixed-power scope and wanting a fast red-dot for close-quarters work, or simply needing an angled Picatinny section for a light, laser, or other accessory, the A645 provides a compact, low-profile solution from a trusted American mount maker.
