The SPECTRA 6X 4.5-27x50i offers the perfect balance between a wide variance of magnification and a slightly larger 50mm objective lens that assists in lower-light shooting environments. This scope is ideal for every game species found in North America, from varmint to elk hunting. The iCONTROL microdot illumination built into the G4i-drop ballistic reticle is sure to speed your target acquisition and help with those longer shots. This scope comes standard with DoubleHD objective lens technology, iCONTROL illumination, PASSIONtrac turrets to assist your shooting scenario, and a MOAi reticle. The turrets, designed for 1/4″ adjustment at 100 yards, provide 70 inches of adjustment range. Custom turrets also are available. All GPO products are backed by the best lifetime warranty and service in the industry, our exclusive Spectacular Lifetime Warranty. The main features of the SPECTRA 4.5-27x50i are as follows:

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.

PASSIONtrac is a unique operating system built into select GPO riflescope turrets. With internal components built from aluminum and brass gearing systems, PASSIONtrac ensures reliable and consistent adjustments when operating the turret. In addition to the high-performance internal components, PASSIONtrac also has a simple turret disengagement feature. This allows the user to reset the turret so the zero-mark located on the turret can align with the zero-indicator mark located on the scope tube body. After sighting in the rifle, the user needs to only lift the turret to disengage the turret threads, rotate the turret to where the zero-mark on the turret is aligned with the zero-indicator mark on the scope body, and gently press the turret down until it clicks into place. This ensures that if the shooter ever needs to make a turret adjustment in the field, they always know where their zero origination began. An additional benefit of PASSIONtrac is its intended use for shooters who regularly dial their turrets. PASSIONtrac turrets are engraved in easy-to-read MIL or MOA markings and follow MIL or MOA point of impact adjustments. Shooters can operate this product like a tactical MIL or a hunting long-range MOA turret: dialing, reading, and shooting. Hunters have the advantage of protecting a dial turret with a machined aluminum turret cap.

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.
