Things I liked: My .22 cal optimus seems like it's pretty good quality. Mounted the scope and had it sighted in about 20 shots. Has good power too.
Things I would have changed: It's a shame the rifle and scope are Chinese made. I bought it thinking it was US made. I would've went with a different brand had I known.
What others should know: This is still a nice air rifle for the price and good for rodent plinking ;) And pyramid air had this at my door in 2 days via their regular shipping. Very fast!
