I wouldn't let it get you down too much - after all, it's always nice to have a choice of different versions of the same weapon: everyone models differently, and the style and texturing of one MP5 might be more suitable for the "feel" of a game than another MP5. I've ended up purchasing duplicate weapon-types simply because the texturing and modelling of certain models matched more closely the vision of my game than ones I had already purchased.
I hope you continue your pack, MP5 and all.
