UPDATE AT BOTTOM

2 color lights in the optics are bright in the house. Have not tested outside yet.
Took this out to the range a few days ago. It was very cold out (below freezing).
Had to start at 50 yards to get on paper. Once I got it pretty close at 50, moved back to 100 yards.
At 100 yards, it seems to be holding, shooting a group of around 1 1/2 inch. Pretty sure that was shooter error due to the cold. Once it warms up, I will do more testing and edit my review if needed.

UPDATE
The very nice time i went out to shoot, the gun was shooting over 1 foot low at 50 yards. Upon trying to adjust it, I found that the elevation knob was free spinning and not adjusting anything. Now it is a large paperweight, since it happened just outside of my return time.

Have to write about this one.
After mounting this scope on my break barrel pellet gun, I shot 3 of 4 shots dead on into the bullseye. Then, it was WHAT HAPPENED TO THIS THING. Shots went everywhere but where I could see them. Finally after 45 yes 45 more shots, I found the target again. Got it zeroed in and then used an old trick someone showed me long ago. Tapped the windage and the elevation knobs with my jack knife and then put the next 15 shots dead on into a 2" area. So many in one spot I had to start shooting into another area of the target and also bullseyes. What was about to be a one or two star rating just became a solid 5 stars. Hope it stays right where it is. Totally satisfied for this price scope. More than I ever expected for the money.

This is a great value scope. It was sturdy enough to withstand my YouTube torture test of launching it out of a water balloon slingshot where it blasted through a branch on a pine tree. The reticle is nice and having the mounts included is a plus. The only fault with mine was the front lens cap was a bit loose, but that could be easily fixed. Overall, it was very accurate on my Ruger 10/22. Dirt Road W.T.F. (Weapons Testing Facility) YouTube channel, video: "TWOD Scope Launch"

Great freaking scope man I don't care what they say about this scope I was thinking it was going to be a little cheap made more for a BB gun or air soft gun but I got it and opened it and let me tell you this thing is a beast looks great feels like expensive made don't know how they can sell this for only $20 but it's are gain zoom is perfect setting it up was super easy and the caps are cool mine was little broken hope they can send me another one that be super but for $20 can't say much this scope looks like a $100 scope easy all in all don't think it just buy it and see it for your self super cool put it on my ruger tactical 10.22 looks sweet

I am completely blown away. I bought this for my little Smith and Wesson M&P 15-22. It's a little AR that shoots .22 bullets. I just wanted to put a scope on it that I could take off and swap with other mods. This scope is really really nice. I paid what ...$37 dollars. I have scopes that cost 20 times that. I did not expect this thing to be as clear as it was. The illumination is nice, really crisp. I don't really use it that much, but it works fine. There are different levels of illumination you can choose from dim to bright. This is a large scope. I knew it would be large, but ...it's really big. Looks funny on the MP15-22. This comes with flip up lens covers which is really nice and worth 37 bucks by themselves. The eye piece and sunshade are nice, but not sure that i'll use them. Maybe down the road, but it's really nice that they throw them in there. If you're looking for a decent inexpensive scope, this is it right here. You can not go wrong for the money. You get the Scope, Rings, Sunshade, Eyepiece extension, and wrenches. Actually, i think i'm going to order another one of these. You can't go wrong. It's nice to just have one around you can stick on a cheap rifle. I'm really happy and a little beside myself. The could charge double for this scope and it would still be worth the money. Just purchased another one to keep on hand. Thank you guys for putting this package together. Nice work.
