Love this reflex optic - Holosun HE508T-GR-X2 1x 2 MOA Dot Green Dot Sights

This has become my favorite reflex optic. It is mounted to a Walther PDP Compact 4” and fits like a glove. I selected this over other reflex optics because of how it is built and the features it has. I am a big fan of the battery tray being on the side as removing the optic every time a battery needs to be swapped requires a bit of work and then going through the zeroing process again. While the battery life for reflex optics are all rated for long periods of time your mileage may vary as it is an estimate based upon intended use.

The automatic intensity adjustment based on ambient light is one of my favorite features, it even comes in ahead of the circle with dot reticle. The 32 MOA circle around the dot speeds up the acquisition of the target for me. I prefer the green dot over red as my eyes pick up the green quicker and it is a higher contrast with all of my targets.

The sight is simple to zero with positive click MOA adjustments. If zeroing at 25 yards, each MOA click results in a quarter of an inch change.

Holosun customer support is excellent. I emailed them on a Sunday morning and had a reply within 30 minutes from a human being who helped to resolve my issue.
