UNS LR-A3 Universal Night Sight W/ACESS, Long Range (Black Unit #2)


UNS LR-A3 Universal Night Sight W/ACESS, Long Range (Black Unit #2)



The high performance unity-power (1X) night vision device allows night operation of any weapon system equipped with a MIL-STD-1913, or STANAG-4694, rail. Mounting options are available for weapons that are not equipped with a MIL-STD 1913 rail in front on the day optic which will provide adequate space for mounting the UNS LR-A3. Any weapon equipped with a Knight’s Armament Company Rail Adapter System (RAS) will accommodate the UNS LR-A3. The UNS LR-A3 primary use is intended to be in conjunction with day optics mounted to weapons as the primary sighting system. The UNS LR-A3 can be mounted forward of the day optic without any adverse effect on the weapon’s Point of Aim or Point of Impact. Verify after adjustments of QD Rail Mount and prior to mission. The UNS LR-A3 does not require any zeroing procedure when installed in front of a day optic. However, the following steps should be taken to ensure optimum picture quality. The controls on the UNS LR-A3 are focus and gain. The day optic, if equipped with a parallax or focus adjustment, should be adjusted to near infinity and parallax free. This allows the day optic to be focused clearly on the back of the image intensifier tube. The focus on the UNS LR-A3 will then be used to adjust the focus of the sight picture.

The UNS LR-A3 is a lighter weight improvement of the AN/PVS-30 Universal Night Sight, Long Range. The UNS LR-A3 adds the latest high performance Gen 3 light intensification night vision to most rifles and day scopes. This product is appropriate for front line long range rifles. The Knight Vision patented technology makes the product universal and assures the accuracy of your range tested day scope boresight will not be degraded. When the UNS LR-A3 is added in front, your existing optic, eye relief, and cheek weld are undisturbed. The refractive lens provides high performance light collection in a light weight design. Knight Vision patented Single Interchangeable Battery (SIB)® allows use of either CR123 or AA single cells, with a battery life exceeding 24 hours, and can be changed while you remain in shooting position. The highly efficient power circuit allows use of depleted flashlight batteries to provide several hours of operation. Single Interchangeable Battery (SIB)® U.S. Patent No. 7,576,516.
