    • Looks nice
Color: Red Green Dot Sight
This looks like a very nice red dot scope, unfortunately it did not mount to my shotgun barrels rail as it is not dovetailed

    • Great blinking scope

I use a ruger 10/22 for rabbit hunting with hounds. My eyes started to struggle to pick up the sights on moving game. This solved the problem! Im right on the money now

    • will not fit the narrow 11mm fixed scope rail on air rifle, just get a adapter and your in business!
Color: Red Green Dot Sight
site states this thing can fit two sizes, IT CANNOT. i read many buyers also complaining and saying it wont fit 11mm, but ordered it anyway. waste of my time. it shows adjustable jaws but once you flip them over and get them set to smaller size they WONT bolt onto the scope base. order them and find out the hard way; your choice. guys saying they dont fit the smaller 11mm air rifle base are right!!! they use deceitful talk to get you to buy this thing. i think it will fit the wider bases though. i just ordered a adapter. i will report back about the adapter after i get it, and see if i can get this sciope mounted using the adapter. scope seems really nice, i hate to turn it back in; especially as it has numerous MOA adjustments even the ultra small moa1 and moa 2 sizes that cost alot on other scopes as well as red and green dot...so i really want to keep this scope. if the adapter works, i will change the star rating. i changed the star rating to 5 stars because i found a strong but ultra inexpensive scope mount adapter that fits perfectly; now i can keep the excellent red dot scope! ... show more

Color: Red Dot Sight
The dot is not bright enough to be seen during the day and the lense is 40mm but the inside of the scope is narrower significantly.

    • Staying on target?
Color: Red Green Dot Sight
Solid quality,easy to sight in but doesn't stay on target. I'm not rough and always store my weapon, I have to adjust down at least 2 clicks after it sits for a day or two.
