German Precision Optics Spectra 4X 2.5-10×44mm Riflescope - RS420
The SPECTRA™ 2.5-10×44 is the base model hunt everything need-to-have premium riflescope. With a 4X zoom factor and a traditional G4 plex reticle, the 2.5 power setting works excellent for close or moving targets while 10x power can reach across the larger fields or canyons for better shot placement. This scope comes standard with DoubleHD™ objective lens technology, PASSIONtrac™ turrets that will assist your shooting scenario and a classic G4 non-illuminated reticle. The .36” at 100y (or .1mrad) turrets provide 85” of adjustment range. Custom turrets are available. All GPO products are backed by the best lifetime warranty and service in the industry, our exclusive Spectacular Lifetime Warranty™.

Features
GPObright is a proprietary coating process that maximizes light transmission through each surface of an optical element. As light hits an optical surface, normal uncoated high-performance glass can reflect up to 5% of that light, redirecting this light so it does not transmit through the optical system. However, when these high-performance lenses are vacuum-coated with GPObright lens coatings, up to 99.7% of the available light passes through each optical surface. Furthermore, when every surface of the entire optical system is properly coated, total light transmission can reach up to more than 92%, making the optical image of a GPO binocular or riflescope “bright,” even in the lowest light conditions.
A Double HD lens is the final product, created when multiple extra-low dispersion lenses are chemically laminated to make a single, multilayer high-performance optical lens. Laminating multiple lenses minimizes light reflection on the surface of multiple lenses, creates enhanced resolution and color contrast images, and minimizes chromatic aberrations. This benefit is clearly visible with all GPO products supporting this feature. This high-performance process is routinely found in the photographic market and with the highest quality photographic lens manufacturers, but has now transitioned into premium sporting optics.
The iControl illumination assures users that they always have a live battery when most needed. – Automatically powers down the illumination when the electronic module has been stationary for more than 3 hours – Offers bright, fiber optic technology – Alerts users when the battery has only 15% remaining battery life.
