One of the best red dots out there, under appreciated for how well done this red dot is made. - Holosun Paralow HS503G Reticle Red Dot Sight

Really a big fan of the ACSS reticle. I think it is one of the most well thought out reticles out there. Takes all the guess work/math out of shooting. The great thing about this particular red dot is the size and versatility. From CQB to pinpoint precision this particular red dot can do it all. Small and compact as red dots should be, very light weight, extremely long battery life, clear glass. You can turn off the CQB horseshoe for a true red dot feel, or leave it on for a reflex sight feel. Combine it with a 3x flip to the side and you have what I think is the ultimate package.

I would not hesitate to buy again for multiple guns.
