Based off the TS Platform, our amazingly unique crossbow/handgun optics are specifically equipped with a parallax preset ideally for the effective range of most crossbows and handguns. They are featured with either Bubble leveler TMOA reticle and PRO 5-step reticle for crossbow scopes or Projectile Drop Compensation (PDC) reticle for handgun scopes for quick aiming at different yardage.
