The SPECTRA 2-12x50i is sure to give you the premium performance you would expect in a low or no light shooting situation. The large 56mm objective lens system transmits an incredible amount of light to your eye while a 2-12 power range gives you ample adjustment for near or far shots. Couple those features with the proprietary iCONTROL microdot illumination, and shot placement on dark targets will make you a believer. This scope comes standard with DoubleHD objective lens technology, iCONTROL illumination, PASSIONtrac turrets to assist your shooting scenario, and a G4i reticle. The turrets, designed for 0.36-inch adjustment at 100 yards (or 0.1 mrad), provide 90 inches of adjustment range.
