Firstly, welcome to the sport
I'm sure that you will love it.
I see that you've bought both the Systema M4 and the MP5,
Would you be able to tell me (or would anyone else be able to tell me) how good it is in a game and if they are reliable?
I saw something about them having to have motors rewound but I have no idea what that is. Would anyone be able to fill me in?
