Absolute Optic Riser

Unity Tactical Absolute Optic Riser

The FAST™ Absolute Riser positions red dot sights precisely at “Absolute Co-Witness” height, which is an optical axis of 2.26? (5.74 cm). The FAST™ Absolute Riser provides an elevated M1913 Picatinny platform for direct mounting of optics such as the EOTech® XPS®, Leupold® LCO®, and other “Absolute Co-Witness” optics. It can be combined with any FAST™ FTC (Flip-to-Center) magnifier mount.

By default, the riser comes with a rail clamp featuring two cross bolts, but it is also compatible with the FAST™ QD (Quick Detach) lever.

If you are using an optic with less than 1/3" of "Co-Witness" height, you will need the FAST™ Optic Riser.

FAST™ is a series of optic mounting solutions that offer end users faster target acquisition than standard mounts. FAST™ mounts create a 2.26" (5.74 cm) optical centerline from the rail, which enables faster visual processing of the battlefield by ensuring an ergonomically correct posture. In addition, it provides the user with greater freedom of movement when wearing night vision goggles, protective masks, body armor, and other equipment.

The FAST™ Absolute Riser is made of 7075-T6 aluminum and features a Type III hard anodized black finish.
