Decent little red dot. - Gideon Optics Alpha Red Dot Reflex Sights

For those looking for a budget friendly option, is a pretty good choice. Note that you CANNOT swap between the dot, circle, and circle dot; the optic only has circle dot as an option. I also noticed some warping of the dot if it gets close to the edge of the glass and from certain angles, the dot is cut off by a hair on the bottom. Ive also noticed that the optic chassis is a bit tall, definitely not cowitness, even when directly mounted to slide. I suggest getting suppressor height sights of you plan on cowitnessing whis optic. The top loading battery compartment is a really nice touch, especially since most budget optics have a bottom loading battery compartment.
