Specifications
Description
The HS510C Reflex Sight has an open frame for a wide sight picture. Always on, it is powered by solar cell under normal usage, and a back-up battery to supplement power requirements in low light conditions. The reticle can be switched between a 65 MOA circle with 2 MOA dot, or a 2 MOA dot only at the push of a button. Better yet, the same LED projects both reticles, so no re-zeroing is necessary.The HM3x is an aluminum bodied 3X magnifier that includes a quick release, ambidextrous, flip-to-side mount with Absolute and Lower 1/3 Co-witness mounting solutions. Additional features include 2.75" of eye relief, IP67 certified water resistance and windage and elevation adjustments for precision zeroing.
