Osprey Global DSMRQR : Reflex Red Dot Sight (4 Dot Size Settings) with Multi Reticle (Dot, Circle Dot, Cross & Double Cross Hair) Quick Release fits Standard, Weaver and Picatinny Rails - 1" MOA

I put this on a Mk IV 22/45 Lite for use in Steel Challenge. It works great, holds zero, and the green really stands out while others are struggling to see their red in sunlight.

Item works and looks great. Was easy to zero and has held zero after firing 2000 rounds with it on my S&W MP15-22.

I have 3 Osprey red dots on 22 caliber firearms...I shoot target. Excellent basic reliable red dot scopes...I have thousands of rounds on both my first 2 and expect the same with the latest 1.......

Bought one at a gun show. I was hesitant, but the guy said they have a lifetime warranty. When I got it home, and unboxed it, the quick disconnect handle fell off. The tapered roll pin was installed backward. Fixed that, no problem.When I mounted it on my AR 9, it was loose, so I had to tighten it quite a bit. This rendered the quick disconnect useless, as it wouldn't loosen enough to be removed from the rail.When I turned it on, I noticed the illumination was not even. It was brighter in the too left corner than the rest of it.First range trip, I forgot the allen wrenches, so I couldn't zero it. I did shoot 100 rounds if ammo just to see how far the sights had to be adjusted. No problems.Second range trip, I started adjusting the sights. I noticed the single dot selection would be blurry every few shots. Also, the brightness in the top left corner became more pronounced.It did hold zero, but I don't have much faith in it with all the issues I'm having. With the lifetime warranty, I hope they'll replace it. But after that, I'm not sure I'll use it.

I put this sight on an AR9 pistol. First time shooting with the sight and the base would not stay tight. Also a part, that appears to be some type of O ring fell off of the sight. The sight doesn’t seem robust enough to use on anything larger than a .22 long rifle. I’ve got an email, phone message, and Facebook messenger in to the company for resolution. Hope to hear from them.Edit: Osprey Global quickly via email and Facebook messenger, and gave me an RMA number to send the sight back. And they offered to upgrade my sight to a more robust model. So five stars for their customer service. I will upgrade this review to three stars due to their excellent customer service.

Bought this item at a recent trade show. The salesperson assured me that the product would work on my shotgun. After the first round fired, the sight got blurry and eventually wouldnt hold zero. Returned the item to the company based on their "Life Time Guarantee" and received a replacement item. That one also turned out to be crap. The company then cease all communication with me. Stay away from this company and the products they sell.
