The BLK Combat Reticle by Pride Fowler Industries, Inc® has been designed specifically for US Optics® as a collaborative effort to offer a mil-spec optic for the .300BLK and 7.62×39 weapon systems. This reticle compensates for both supersonic and subsonic ammunition and provides other critical ballistic information that will reduce engagement time and maximize the performance of the weapon system.

In addition to holdover data, the BLK Combat Reticle will provide instant ranging on 9”/18” objects (Rapid Ranging), Mil-ranging, wind holds out to 10mph, and impact guidance for low magnification utilization (Rapid Guide). Right side data is specifically for 110 to 125gr ammunition with a 16” barrel weapon system shooting out to 700 yards. Left side data is for use with 220 to 225gr ammunition and a suppressor shooting to 350 yards.

Combined with the superior quality of the US Optics SR-6, the USO—PFI-BLK optic system is rugged, reliable, and greatly enhances the .300 BLK weapon system.
