XD Lens Elements  |  Extra-low dispersion (XD) glass increases resolution and colour fidelity, resulting in crisp, sharp images.
XR Fully Multi-Coated  |  Proprietary coatings increase light transmission with multiple anti-reflective coatings on all air-to-glass surfaces.
Second Focal Plane Reticle  |  Scale of reticle maintains the same ideally-sized appearance. Listed reticle subtensions used for estimating range, holdover and wind drift correction are accurate at the highest magnification.
