The PVS-22 is designed to mount on any MIL-STD-1913 rail interface forward of an existing scope, adding night vision capabilities to target acquisition platforms. It offers mission flexibility as a high-resolution night vision weapon sight, mounted on a spotting scope for long range reconnaissance, hand-held as an observation device, or used in other night-time operations requiring night vision capabilities. The unit is effective on all weapons from carbines to .50 caliber semiautomatic and bolt action sniper rifles, including the M110,MK11, M16, SCAR-H, M240, 300 Win Mag, XM107, .300 Lapua, .308 M24, Chandler, and McMillan Brothers. The system includes FLIR’s proprietary Shock Mitigation System™ (SMS™), allowing the unit to be used on weapons up to and including .50 caliber bolt-action rifles. The UNS is a highly portable design and reduces operator fatigue. It's large, rugged controls make it easy for basic image adjustment, requiring no complicated menus to navigate and it runs on common AA batteries.
