I don't think you would want a power cord going from your vest from your rifle. If it gets caught on something you either get stuck or your rifle loses power.

There is a lot of work on making a powered accessory rail for rifles though, so that everything on it would share the same battery. I thought that battery would always be on the rifle though.
