Quick-pointing, precision accuracy, from close quarters out to 400 yds. For military and law enforcement personnel, close doesn't cut it. You need to be dead-on when it counts.

Its P3TR illuminated reticle gives you 11 levels of brightness to match any conditions, from bright daylight to low light and night vision. 1x magnification gives you two-eyes-open situational awareness for close-quarters engagements, while 4x zoom capability provides pinpoint accuracy out to 400 yds. Sleek, no-snag design ensures you won't get hung-up while maneuvering, and rugged, waterproof, fogproof/shockproof construction delivers performance you can count on in cold, wet conditions.
