If you're wanting to give your M14 replica an Enhanced Battle Rifle (EBR) look, rather than getting a full EBR replica, you can purchase the KART M14 EBR Short Barrel Conversion Kit available at RSOV.com. This is basically the EBR chassis with which you can pop-in your M14's receiver, gearbox, fix the wiring, and viola! A new look for your M14. But it may take more than just popping in the receiver and be prepared to do some nip-tucking to get the right balance and fit.
