One thing that I am a bit surprised has not been mentioned here is just how much out sourcing there is in the production of AR platform rifles these days, just look at all the Magpul branded parts you see on many brands of AR's, the limiting factor on the production of these guns may well be the availability of such parts, I therefore suspect we will see some new volume production models introduced soon that bypass many of the 3rd party parts bottle necks by using imported replacement parts, etc..
