The Holosun HS503CU is the red dot we here at KTactical want to use in our rifle builds.
Not only does it have the added benefit of solar power, but the HS503CU model specifically has the ability to switch between a single dot reticle (for long range precision) and a larger, circle dot reticle (for close engagements).
This is a great optic to mount on any rifle or airsoft gun and is highly recommended by our team!
