Designed as a reduced-weight professional marksman riflescope, the TT315M incorporates precise adjustment mechanisms with zero stops and mechanical revolution and windage direction indicators that virtually eliminate adjustment errors. The optical path has been optimized for unsurpassed image quality, allowing the marksman to see minute target detail and to remain in the aim for extended periods without eye fatigue.
