As small as a matchbox and no heavier than a single .45 ACP round, the UNI series adds error-free precision without weighing you down. Featured advanced programming and an integral rail for the attachment of additional accessories, a UNI fits virtually anything with a Picatinny or Weaver rail. Attach one to your pistol, carbine, tactical shotgun, MSR, paintball gun, archery equipment, or find an entirely new use for this revolutionary stackable rail interface! Windage and elevation settings are easily adjusted to accomodate any platform at any distance. Replace the UNI's mechanical switch with a Momentary Activation Switch (MAS) for comfortable pressure activation from almost any angle or position, even with gloved hands.
