The Warne 45-degree offset Picatinny side mount adapter (Warne part no. A645TW) is a compact rail that angles at 45 degrees off your top rail. It gives you a place to mount a secondary sighting system or another accessory without crowding the main optic. Warne machines it from lightweight aluminum in black, and it weighs about an ounce. It is made in the USA and is aimed at shooters who run back-up sights on an AR upper or any Picatinny rail.

Key Specifications

• The mount angles at 45 degrees, which offsets a secondary sight so it stays out of the way of the primary optic.
• The interface is a Picatinny rail, so it accepts the same sights and accessories as a standard 1913 rail.
• Warne lists it for AR uppers and Picatinny rails, the two platforms it is built to attach to.
• Construction is lightweight aluminum, which keeps added bulk to a minimum.
• The finish is black, matching most rifles and optics rails.
• Weight is 1.0 ounce, light enough that you will not notice it on a carbine.
• Warne designs it for back-up sights and secondary sighting systems, the use it is named for.
