Tangent Theta's TT315P 3-15x50 riflescope with Gen 3XR reticle was designed as a major refinement in long-range precision sighting for professional marksmen. Intended for heavy field use the TT315P provides excellent light transmission and a crystal-clear sight picture. The TT315P uses an advanced Gen 3 XR reticle which is built around a center dot for a precise center aim point. The crosshairs feature 0.2 MRAD graduations which increase in size from 0.2 to 0.8 MRAD with each dot indicating a full MRAD. Directly below is a "Christmas tree" style holdover reticle giving the user up to 10 MRADs of elevation holdover on the crosshair in addition to 5 MRADs on either side for windage. The TT315P is also equipped with windage and elevation mechanisms that give exact tactile responses and can be re-zeroed without the use of tools.Features of the Tangent Theta TT315P 3-15x50 Riflescope:34mm main tube50mm objective lensSide parallax adjustmentIlluminated reticle (11 settings)TOOL-LESS RE-ZERO featureNon-translating knobs with elevation zero-stop3-15x magnification rangeLockable rapid adjusting diopterDouble-turn elevation with revolution indicator
