SANYAN 1x40 Tactical Holographic Reflex Red Green Illuminate Dot Sight Scope Hunting Optics Riflescopes External Adjustment

I read some of the negative reviews on this red dot and I figured it was no big deal if the thing ended up being a piece of crap. Well, it's not! I really love it on my AR-15. I have a front-sight post so I could not mount it on top. I purchased the 45-Degree Offset Angle Rail Mount Picatinny from Amazon (B01N1RGWXH) and mounted it at an angle. I zeroed after 6 shots and it kept the zero through all the rounds I fired. I will buy again when I build another AR. Turn the dial one direction and you get a green dot, turn it the other way and you get the red dot, with 5 different intensities for each one.

Absolutley splendid for airsoft purposes and minor airgun usages however i dont reccomend this for real steel firearms as the recoil of some firearm calibers tend to make it go off center and not by a large margin but more of you wont notice it until after a few rounds cause its so tiny of a movement. Other than that airsofr or airgun it works just fine even works good with additional attachments on your rifle you may have. And lastly its not too big for a Lens protectorUpdate: if you use this for airsoft get a lens protector regardless i had one on there so i was fortunate. Also this is pretty good with being shock proof seeing as i dropped my gun right on my sight into the dirt and it still function not only that but ut also stayed on the zero so it didnt have to be adjusted at all its very good and i reccomend it

laser sighted and bore sited this on my 22 lr. Yes it will fit a 11 mm rail, you have to reverse both dove tail sections to fit the 11 mm. Many stated it will not fit. I would bet they reversed one side only. Fit great and tightened down great. One downside is the switching fro red to green. Dot does not hold zero when switching red to green, so choose one and stick with it. I am planning to buy another one for the other 22 lr. I also want to see it in action at night when using a light to illuminate the target.

Guess what ? It fits on a 3/8" dovetail mount for a pellet gun !!! First time I shot it the rubber band came off and the second time the bubble wrap got in the way. But over all it is good except I would prefer lockdown adjustments--I get tired of adjusting between every shot-Ha-Ha. Just a good fit on my Sheridan squirrel rifle. Good buy indeed >>>>Also helps hit moving empty(of course)beer cans around the old campfire.

wish it had more dot adjustment on size

Awesome . Love it and use at steel and uspsa challenges. 22lr to my 10mm race gun. Works great.. only down is red and green dots dont match and shift.. so I use only the green. Only since that is the color I zeroed with . And green is better for day use

I would have given 5 stars if it fit 3/8 dove tail(11mm mount) it fit slopy and would not stay in place, but I will adjust and keep it because the price is right!!

I bought this to use on a nerf gun, I works good for that. I like that there is 10 different setting for the reticle, 5 being green, and 5 being red.
