I would have loved to see the AR upper/lower be reworked into a complete upper from butt to muzzle and a trigger pack a la HK. There's no need to have multiple magazine wells when your upper is going to stay one caliber anyways.
The AR-15 has impressive customization but having the buffer tower be a part of the lower is the number one thing getting in the way of true creativity.
Imagine the same trigger pack being compatible with everything from an MP5 sized subgun to a fucking Kord-style belt fed shoulder fired .50 bmg.
Of course faggots will make the upper the serialized receiver but a man can fucking dream.
