Things I liked:30 Round pellet magazine.I was amazed that there was no jams or mise fires as of yet,and I've fired approx.20 clips.Excellent ! Feels as comfortable to shoot as it looks,and it looks great. Things I would have changed:So far the only thing I would change is a way to load this "high round" magazine quicker.Also,more power,600 f.p.s. is good,But I would like to see more. What others should know:If you can buy the whole kit because your going to find that you want more anyway.
