Things I liked: They are the only game in town for the Benjamin oistol.
Things I would have changed: The screws are very small and break as they tighten up. I drilled the holes out and used #8 socket head screws.
What others should know: This is not a very good mount and also puts the sight far above the bore axis. A better mount is needed but I don't know where to find one.
Things I liked: Inexpensive, easy to mount ,
Things I would have changed: The provided rings are for a Weaver rail and will not fit the 3/8 dovetail on most airguns. The dot is more of a 6 MOA blob. I looks better in the sunlight and is fine for plinking.
What others should know: This is a good compromise between cost and performance. It has worked well so far and I purchased a second one for a rimfire pistol.
