Add To:

The Holosun HS510C 2MOA Red Dot Reflex Optic and the Holosun HM3X Magnifier are now available in an excellent combo package.

The HS510C Open Reflex Circle Dot Sight has an open frame for a wide sight picture. 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, a 2 MOA dot only, or a 65 MOA ring only at the push of a button. Better yet, the same LED projects both reticles, so no re-zeroing is necessary.

The HM3X line of magnifiers will allow the operator to seamlessly transition from unmagnified to 3X magnification. The new Holosun HM3X features an adjustable diopter to dial in the desired focus, extremely clear glass and very generous eye relief. Mounting options include an integrated QD mount with an optional spacer for Absolute Co-witness and Lower ⅓ Co-witness. Holosun’s HM3X comes in a durable Aluminum housing.
