Ade Advanced Optics Mini RD3-006x Green Dot Reflex Sight for Colt 1911 Standard Pistol Mounting Plate That Replace Rear Sight

This is the one to get if you are on a budget!!! It's rated up to a 9mm, but I put double sided gorilla tape between the mount and gun, also used the rubber piece... mounted it on My .45 acp, 1911... Mrs Jones 😆 I've had zero problems with this sight... I've put a few boxes of cartridges through her...

On my 1911 it not easy to line up the eye with the red dot. I hope i can overcome this with more practice, if not I'll buy another base and try ot on a long gun. It solid built

Installing on a Charles Daly 1911. The C.D. claims to have 'Government sights'. The wedge did not fit at all. I had to perform considerable filing to get it to fit. Than came the greater frustration. The mounting screws countersink is far too deep. The chamfer of the mounting screw bottoms against the wedge before the sight base gets tight. I have filed the top of the wedge almost level with the slide but still loose. The machinist really messed this one up. These screws are so deeply countersunk I could probably replace them with panheads and they would still be flush. I tried using the longer set of screws that mount the sight to the sight base. Hoping that they would go all the way through and push against the slide to secure it. That did remove the wobble from the sight but made it point so high I doubt it can be brought back down to alignment. I am a novice gunsmith. Trained in the U.S. Army on small arms repair. This sight is frustrating me badly. Summary - do NOT buy this sight.

Built very well, wish the green dot was brighter. Will try a fresh battery since they are cheap and easy to replace. Great value for the money.

Really wish I didn't waste my money on this this sight is just not built well on my second one and it already stopped working u get what u pay for

No instructions on how to mount on 1911. Found video on YouTube. Would probably rate 5 stars if adequate installation Instructions included

Great sight but unfortunately there was not enough windage adjustment for my 1911. I returned it for the next size bigger and it works perfectly.

This is one of the best red dots you can buy for under 100$ I use it on my Colt 1911 .22 it is easy to set up and use and I enjoy how bright it is on a sunny day. After zeroing be sure to set the screws with locktite and it should stay zeroed.
