    • 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

    • Low cost good quality
Color: Red Green Dot Sight
Used on pellet gun. The scope slides while mounted so it don’t fit the best. It’s cheap and looks great. I had to add a piece of wire under clamp for it to be stable. It’s still worth the purchase. Just buy it. Honest review.

    • Check for adaptability first
Color: Red Green Dot Sight
This 11MM rail Dot sight sits on a BB gun. Appears to be OK, not expecting much from a 20 dollar red dot. Its sole purpose is to assist in squirrel reduction.

    • Buy the dovetail to picattiny adapter
Color: Red Green Dot Sight
The actual optic isn’t bad, surprisingly clear. If you’re buying this for a dovetail rail just save yourself the time and buy an adapter. I can’t get it to attach to my dovetail .22 securely even if you flip the mounts over. I would’ve rather just bought the adapter with the optic and been done but here I am waiting. ... show more

    • Dont buy
Color: Red Green Dot Sight
Not funtional for shooting. Red dot is hopelessly misaligned and the adjustment knobs don't work. Instead of moving the laser they move around an arbirtary ring in the scope which does nothing

    • 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.
