Ump stock help!

[JMM990]

Heya guys and gals. I've recently bought a g&g ump, and totally love it apart from one minor gripe. The stock. It's slightly too long for me to shoulder comfortably, and I'm not 100% sold on the way it looks.

Is there anyone out there that sells conversation kits for say, an m4 style stock?

I did see a real steel one converted with a Masada stock, but unless I find one cheap I wouldn't feel comfortable cutting one up.

I don't really want to modify the receivers, just the stock

Thanks guys
