The Spectra 5X 3-15x56i by German Precision Optics is a versatile riflescope ideal for long range hunting scenarios. Like all the products offered by GPO, the Spectra 3-15x56i offers excellent optical performance. This is thanks to GPObright lens technology – a vacuum applied coating that allows 99.7% of available light to pass through each optical surface, resulting in a light transmission that can exceed 92%. Optical performance is further optimized by DoubleHD objective lens technology to enhance optical resolution and image quality, and a 56mm objective lens promotes brightness even in low light environments.
