I am trying to decide bewteen buying a MP5A5 or a MP5A4 for CQB. Does anyone have any experience with the MP5A5 sliding stock? When I look around at MP5's, most people have A4's, and those are the only MP5's I have handled (and SD5's) I was at a local gunstore, and they had an Airsoft Elite MP5A3, and the stock felt pretty sturdy. My main question is, will the paint start to chip over time because the stock slides, and will it become loose.
