    Looking through the scope, you can see the distortion around the edge of the lense. The center is clear and sharp, but the edge of the viewing lense is not. The mounts will collapse down to fit an air rifle, as well as a 22 rifle.

    Managed to fit the scope on my 1.77 daisy red rider steel bb rifle instead of returning it

    I bought this for cosplay and not for a functional gun of any kind . That being said it looks good ,and seems durable. It also,looks exactly as pictured. Shipping was fast, one side of the country to the other. I will probably pick up another for another project.

    Good for young kids

    Removed from my rimfire 22 caliber rifle as it is small for a grown man. Installed in an air rifle. Good for young kids with good eyesight.

    Do not buy this!!!...

    Most scopes come in the middle so when adjusting elevation or windage...you can go up or down..this scope came at the most down position of elevation so I could only go up..but my first 5 shots with it had it 6 inches high of my target at 15 yards!...so there's no way to bring It down...it only goes up...whoever made this messed up its original calibration now I'd have to pay the shipping to get my money back which is probably more than the 11 dollar scope so really I'm getting screwed! Horrible horrible horrible! Oh and just got off the phone with the warranty people...I'd have to pay more than what the scope cost to get a replacement shipped to me. Out of the box the optics were completely not centered..no way to zero it in at all..loss of money for me. Will never buy from them ...

  • Can't be mounted on Marlin .22

    I bought this scope to mount on my Marlin Model 800 .22. The rifle was for my son. It was my rifle as a kid and it was given to me by my dad as my first rifle. I was giving it to my son. Unfortunately, the scope could not be mounted to my rifle, despite the description that says it can. In the process of trying to make it fit I scratched and damaged the rifle. The scope is cheaply made and I would not recommend it to anyone. Then again it was cheap..... You get what you pay for.

  • Do not bother...

    looks nice but... the construction is cheap cheap cheap! The cross hairs are crooked! The only way to position them correctly is to rotate the scope so that the turrets are out of their vertical / horizontal planes. Spend a little extra and buy a "cricket" scope. Merry Christmas

  • Compact tactical scope

    This scope is not that good because of the small size and when you look through it you can barley see 20 yards!
