As a gunsmith, here is some real talk…. - ADE Advanced Optics RD3-012-PRO Series Motion Activated Red Dot Sight

Let me give you some real talk from a professional gunsmith. The reviews that say this is a good “entry level” red dot are written by folks that are trying to sound like they know more than they do. There is no such thing as an “entry level” red dot…it’s either a red dot sight or it isn’t. You don’t need a master’s degree to operate one. Folks that give a bad review because it didn’t fit, didn’t pay attention when they ordered it. Know your weapon. Understand the “footprint” for red dot sights and order accordingly. Don’t blame the manufacturer for your own laziness or incompetence.
As a professional gunsmith that spent 8 years in the Marine Corps and worked in law enforcement, I can tell you that this is an EXCELLENT gun sight. It is compact and well made. It fits the footprints that it is designed for PERFECTLY, and securely. It zeros easily and maintains zero after heavy use. The quality meets or exceeds any of the $400 rip offs out there that are selling you a name brand as much as a gun sight. I would buy this any day over the others and use it to compete against anyone using a high dollar version. And I would win.
If you want to spend your money just to keep up with your friends, suit yourself. If you would like to have a quality red dot sight at an extremely reasonable price, then this is what you need. Now that’s real talk.
