The Stock BK2s is decent, but I felt it needed a longer stock, and a different more ergo friendly front end. However, the main problem I had with it was the battery access and tray. I was very limited to what batteries I could use, and how hard it was just getting in/out of the battery tray. So here at XFoxGames we went ahead and created a body kit that made it feel a little more user friendly, while giving it a sweet look!
