ADE RD3-006 Green Dot + Optics Plate for Colt 1911 with G.I 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... Update; Not only is the sight a great deal, I've had it for about a year, and have had no problems with it at all.... Till last week, I went out to shoot in the cold weather, and when I shot the lens shattered... So I messaged them, and they sent me a new sight in less than a week!!! Fantastic customer service!!!! Upon writing this, my Son just informed me that he had dropped my gun, prior to my shooting her.... so it very well could have had a crack that I didn't notice before shooting her.... Either way, it's a great sight especially for the price, and customer service!!! Update; I just can't say enough about the absolute fantastic customer service! I messaged them about the shims that they offer for free, and they responded the next day, and said that they are in the mail... They didn't even charge for shipping me the new sight, and I had it within a week....

Unboxed this thing and it is absolute garbage the adjustment screw for left to right will only go to the left. It will not move the green dot to the right whatsoever and you’re up down adjustment on it, The screw actually split when I was adjusting the elevation absolute garbage!

It's a quick acquisition scope.....how else do I describe it.

Super bueno

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.

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

Absolutely great. Works a charm.

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.
