Holosun is my preferred 'red' dot sight brand (I use their green variants). Fantastic combination of function, features and price. The newer solar-powered SCS I bought for my Glock 17 MOS is **** near perfect and looks like a factory part.
I've had four Holosuns at this point (and a few others from different companies). Reflex sights in general are indispensable for an older guy like me with astigmatism.
