TrackingPoint AR Series - Testing
TrackingPoint™, creator of the world’s first Precision Guided Firearm (PGF) system, announced the debut of the TrackingPoint 500 Series ARs for the modern sporting rifle market at ShowStoppers @ CES 2014 in Las Vegas. The three PGF rifles, offered in 7.62, .300 BLK and 5.56 calibers, incorporate the company’s ground breaking Tag Track Xact technology, accurately locking onto and hitting moving targets at distances up to 500 yards. With stabilized target selection, target tracking and guided firing the 500 Series semi-automatic AR products enable anyone to be an expert marksman out to the 500 yard effective range of the firearm, even from difficult firing positions, such as kneeling, standing or even lying beneath an automobile. http://tracking-point.com/labs/ar/
