The 1x/4x32mm PSU, WPA’s flagship scope, was designed to combine the best features of both the 1x and 4x sights. When set on 1x, the PSU provides a huge 26 degree field of view facilitating rapid “both eyes open” target engagement. Set on 1x it can be employed similar to a reflex sight, providing quick hits on multiple or fast moving targets. With the flip of a switch the magnification increases to 4x providing target identification, ranging and engagement at extended distances. A Bullet Drop Compensating reticle combined with a simple to use “no math” telemetric rangefinder provides fast and reliable hits.

Built to survive harsh conditions the PSU is manufactured from a solid aluminum alloy body. The design is both shockproof and watertight. The fully multi-coated optics provides a sharp and bright image with accurate color rendition and excellent resolution. The illuminated reticle features seven intensity settings and is powered by a readily available CR2032 3-volt battery. The BDC reticle provides ballistic compensation out to 800 meters. The telemetric rangefinder allows ranging out to the same distance. Capped adjustment turrets provide quick and trouble free zeroing. Once zeroed all ballistic corrections are made using the reticle.

Very compact in size, the PSU is only 7.4 inches long. Weight is just 24 ounces. Eye relief is a generous 2.75 inches. The PSU mounts easily to a MIL STD 1913 Picatinny rail and features two QD levers. These allow rapid attachment and removal, no tools required. Extremely robust, the PSU is a perfect match for an AR-15 or other Modern Sporting Rifle.
