Things I liked: The mount is very adaptable to anything that you have, and it's very strong. The red dot is easy to find and use.
Things I would have changed: I don't know if it's possible, but I'd like a faster method of turning the red dot on or off.
What others should know: This RD30 is very high quality and I mounted on my Gamo Shadow Express. Using Dirty Bird targets, it's deadly accurate.
