The wonderful thing about AR platform rifles is that they’re so easy to customize. Using a detachable rear sight for AR 15 is a popular choice for many shooters. Del-Ton, Inc. offers a variety of Picatinny rail-mount rear sights. If you want flexibility, a detachable A2 rear sight is just the ticket. Picatinny rear sights mount easily where you want them rather than forcing you to assemble your system and accessories around them as with permanently integrated sights. Whether you choose a standard sight picture or a di-optic aperture Picatinny rail rear sight such as the Troy Battle Sight, Del-Ton has the sight you need to complete your system.
