What marksman said ;-)
While it is one of TM's best M4 versions, it will have a plastic body and therefore not be as robust as a metal one. Some guns are great in plastic (G36, P90 etc) but the design of the M4 means that you'll have to be careful with it. I've seen many a front barrel snapped off!
Better off going for a G&P full metal up front, then upgrading the hop for Marui like performance. Especially when they're not much more new!
