Awesome value - Gideon Optics Omega Red Dot Reflex Sights

Using as an offset 45 on an ar. Cant speak to the durability over time, but came dead nuts at 15y from factory and held zero over 400 rounds so far. That dot is crispy and the battery door is accessible from the top. Surprised at the build quality, glass clarity, and dot crispness for $200. Not sure how it would hold up on a reciprocating slide, but should be great for this application.
