career 50cal new model

i was just wondering what you guys think about the 50 cal the new one with the cocking lever and single tube. like how well built is it and what are real world velositys, and how easy can you modify it. i like this design a lot better than to old ones. i just wish they built a 9mm with the same design so you could get higher velositys. i am just worried that the pellet will drop like a rock, and it cost a lot. thanks for your input.
