The patented Rapid Reticle BDC reticle offers critical information that is clearly translated for impact guidance that considers multiple bullet weights barrel lengths and elevation changes. Our BDC design features several innovative proprietary technologies that enhance the performance of the weapon system expediting target acquisition target ranging and target engagement. Rapid Ranging provides an instant distance approximation for 9" and 18" objects within the reticle.
