Hunters and precision shooters alike can find a Bushnell Nitro riflescope to fit their needs. All configurations are built to withstand every environment. The fully-multi coated optics deliver bright, high-contrast images with minimal eyestrain. Whatever the scenario, Nitro riflescopes have a solution. All exterior lens surfaces have EXO Barrier coating. EXO Barrier, quite simply, is the best protective lens coating technology Bushnell has ever developed. Added at the end of the coating process, EXO Barrier molecularly bonds to the lens and fills the microscopic pores in the glass. The result is an ultra-slick coating that repels water, oil, fog, dust and debris - rain, snow, fingerprints and dirt will not stick. EXO Barrier is built to last: the bonded coating will not fade with the passage of time or normal wear and tear.
