The HS507COMP combines an oversized window, premium reflective glass, and the new Competition Reticle System to deliver prize-winning clarity and performance for the competitive shooter. Innovative Shake Awake technology brings the optic to life with the slightest movement, meaning no fumbling with controls. Once "awake," the Competition Reticle System provides your choice of 2 MOA dots, 8 MOA circles, 20 MOA circles, or 32 MOA circles with multiple combinations to help get you on-target in a competitive setting.
