Beileshi Red Dot Sight, 4 MOA Compact Red Dot Gun Sight Rifle Scope with 1 inch Riser Mount

Easy to install and works great, definitely worth the price. I wouldn’t pick any other on Amazon as I had multiple ones for similar price and this one works flawlessly

I'm not going to give be this a one star review, but I can't give it five stars, either! It didn't fit the gun I bought it for. Apparently I have the 11 mm rail, not the 20 mm rail. The description should say what size rail the sight would fit. I couldn't find a thing. Now, I'm faced with having to return this and order another sight that looks like it will fit. I love everything about the current sight. The brightness levels are easy to adjust, as are windage and elevation. I haven't been able to make the dot change colors as it is supposed to, but that is an experience factor. It has just enough weight, and the overall build does not make it look "cheap." All in all, it's a great sight; I just can't use it. UPDATE: AT THIS TIME I HAVE DECIDED TO NOT RETURN THE ITEM, AS I MAY HAVE FOUND A SUITABLE SOLUTION TO THE FIT PROBLEM. UPDATE 2! I ordered an adapter rail which fits the 11 mm dovetail mount on my gun, going to 20 mm for the sight. The sight now mounts to my gun and I can use it. I'm upgrading my review to five stars.

I’ll start this review by saying that this is a perfect sight for indoor airsoft, and I love it. It’s easy to install and fits nicely on the rail. It’s also very high quality both in battery life and build quality (although I’m not sure about recoil on a high caliber firearm)The only thing that keeps this from being a 5 star product is the size and riser. The sight itself is pretty small which is fine since it’s meant for close up view, but it also sits really close to the rail (which is good for accuracy, but the view is blocked by integrated front sights like the A2), and the riser it comes with helps this but at the cost of accuracy. Other than that it’s a great sight for the price, but I’m not sure about the accuracy and performance on a real firearm.

Cheap as dirt but not bad cheap . Great for practice or training . I mean it’s easy to use nd doesn’t fall off . Battery is cool, just turn it off manually and you won’t have any problems. Last you can turn the brightness down so it looks less blurry so I don’t know what queens up here saying it’s terrible but remember it’s 20 dollars so let’s not compare it to 800 dollar set ups

very happy for the price, great value. sighted in nicely. Easy install

This is by far the best laser scope I have ever owned it works well at 30 up to 100 yards

I have bought like 4 of these. One has died. All the others are fine. They have a bit of a parallax issue. They do hold zero though, and are fine for plinking guns. The retical can get ridiculously bright which is great for winter shooting. It's easy to leave them on and kill the battery.

A lot nicer than I thought easy to attach just got to sight it in and boom on target I give it a four on the line up can be a little frustrating with windage and drop
