Things I liked: It allows me to shoot longer pellets such as the predators pr logan penetraters.
Things I would have changed: I was suprised this thing was made out of plastic!!! For the price, i expected it to be machined from a chunk of aluminum or steel. Ohh well.
What others should know: Its plastic. Just so you know. Not a bad thing, i mean,.... It does its job, its not going to break or fall apart, but i hate plastic.
