EOTech's HHS Complete System is the perfect aiming solution for shooters who need to rapidly transition between close and long range shooting. The HHS Complete System is composed of two parts; the EXPS3 holographic sight and the G45 magnifier. By itself, the EXPS3 is an exceptional close quarters sight. This holographic allows users to engage fast moving targets with both eyes open and features 20 brightness settings and 10 night vision compatible settings. Should need to engage targets at longer range, the G45 magnifier can be rapidly deployed to provide 5x magnification.
