Honestly, I'm going to review this gun in sort of a two part. While it functioned, it performed very well. Unfortunately, I believe I got a lemon. The ATP was extremely comfortable, was very gas efficient, and very accurate. Up until the day it stopped working, it was an absolute powerhouse. But out of nowhere it stopped working. The slide wouldn't rack back when fired, and eventually just literally locked up. We checked all the springs and stuff and could not find anything wrong with it. It just stopped working after like two months. So I won't say that this is a terrible gun. Many people use it and it performs great. But unfortunately I was let down with my purchase.
•EXTREMELY comfortable and ergonomic
•Very gas efficient
•Easily removable and reattachable orange tip
•Hard to find replacement parts for it when mine went down
•Hop up adjustment is kind of annoying
•I got a lemon-_-
Don't discount this gun totally. I can't say that the ATP in general is bad, but sometimes you have to be a bit careful with KWA because of how brand specific and what not they can be.
