Excellent multi-featured reticle. I use this on a few pistol crossbows that I have. The reticle required a dovetail-to-picatinny adapter, but it was a cheap and easy fix. The reticle features five distinct shapes for your crosshairs, from circles to a simple dot. Also, the reticle offers both red and green colors in five progressive brightness intensities. I am not a gun owner, so no word on how this performs with an actual pistol or rifle. But, for my purposes (which rarely amount to much more than goofing off), this reticle makes things fun and easy at short distances with my crossbows.

Bought it as a gag gift for a friend, he loves it. Its so bad lmao! The windage/elevation screws do literally nothing, and itd probably break the lense if you looked through it too hard. He sends me pictures of it in places it doesnt belong captioned "call of doody"

It works. You get what you pay for. This does have the selectable reticles via an easily accessed switch on the rear of the unit, and the various intensities in both red and green light via a rotating dial on top (that turns a little stiff, but it's brand new so maybe that'll wear in after awhile?). My concern is that the image on the glass is not as clear as I was expecting. Adjusting the intensity of the reticle helps only so much. When paired with a home defense integrated weapon light that puts out up to 600 lumens, this sight's illuminated reticles can still be clearly seen. Missing a star for the some what blurry image. Due to the price and the options of variable color and intensities, I'd recommend this product, just barely. But I'm picky. I'd like to have just one more feature ... an on/off toggle or push button on the back so the selected color, intensity, and pattern is instantly on and off, with out having to dial through the various intensities. But that's a feature on the more expensive models. Again, you get what you pay for.

I am using this sight as a telescope finder scope and I am very impressed with it's capability, I 3d printed an adapter for the old finder mounting hole to the Picatinny dovetail and this mounted perfectly. This is so much better than the telescope red-dot finders out there since you can change to red and green and cross or circle instead of a simple red dot. Compared to the Celectron red-dot finder I used in the past, this far exceeds the usability, is well constructed and very robust on my telescope and has a much wider field of view.

This little red dot sight really improved my marksmanship with a Ruger Mark II with a 6" Pac_Lite custom barrel. It fit perfectly on the rail mounted to the barrel. I sited it in with my laser bore siter from the same company. The pistol was already accurate with the iron sites but this just makes it so much easier. There are a lot of these sites available with prices up to hundreds of dollars. This one works as well as any I have used and for a fraction of the cost. I would definitely buy another one if this one should get damaged. ***UPDATE*** I received this Red Dot sight on my birthday. I couldn't wait to get it out to the range and as you can see from my review above, it did not disappoint me at all. On my second trip to the range I noticed some movement and tried tightening the scope mount but it was not loose. Turns out the rail on the new barrel was loose. I sent it back to the factory and it was properly repaired. I just got it back and now it is ready to go again. Note that even while there was a small amount of movement in the rail, I was still able to maintain a reasonable grouping at up to 25 yards. The one's I missed had to be from the loose rail. At least that's my excuse and I am sticking to it. )) From now on though I won't be able to use that excuse. At least with this new reflex sight, I won't need as many excuses as I used to. I still absolutely would buy again if something happens to it.

This sight is all I could have asked for, especially for the price! 2 colors, 5 brightness settings, and 4 reticles. It gets bright enough to work during the day and looks very sharp at night. The laser does its job, but I wouldn't really recommend using it during the day because it isn't crazy bright. My first unit had a bit of blurriness on some of the reticles, and the AMAZING customer service assisted me very quickly and handled it perfectly. Would buy again, and I highly recommend!

it gets one star only because it turns on. adjustments just move how they want, no control of left/right/up/down. does not hold zero on an airsoft rifle or a crossbow pistol so it has no chance of holding any zero on anything. it MIGHT hold on a bb gun but getting the adjustments to even get to where zero is would be a several hour task and you would need some serious luck. monstrum has a .22 red dot that is $10 more than this but has monstrum backing it so its going to be great and their support is unrivaled. save the $$ and skip this one

so i bought this sight and i had high expectations, everyone says ohh you need a 50-60 dollar sight for it to be good or last long, etc etc, i bought this sight for 21.99 and this thing is a beast, I play air soft a lot and im worried this sight will get shot out so im going to buy a protector for it but i was worried if this sight would be bright enough, when pointing at something in broad daylight i had no problem seeing the red dot sight, i play in an indoor field and its a little dark so im probably going to stick with the '1' setting because 5 is super bright and i dont think ill need it, also 4 choices of red dots and they can also be green, i like green way better, and this thing feels as solid as a brick, full metal except for this little hump at the back of the sight shown in the picture, the one thing i did have a problem with the adjustment screws say up and point to one direction but when u turn the other direction it was up, so make sure u know that because yours might be the same and u might think its defective after i found that out i had no problem adjusting my sight, works very well!!
