The AEX 45 degree angle mount is a machined aluminum picatinny mount that attaches to any picatinny rail surface and creates a 45 degree picatinny mounting surface. Ideal for anyone looking to attach a back up red dot sight, iron sight, laser, or flashlight. Use it to optimize placement of a laser or light illuminator, or to accommodate a large diameter flashlight on your mounting rail. For a scoped rifle, use it to place a back up red dot or iron sight on your rifle to address close quarter targets. Uses for the 45 degree angle mount is limited by your imagination.
