Interesting.... 1 lower, multiple uppers, multiple calibers. Ignore the Colt vs. LMT vs. whoever battle and look at the concept here. Going back & forth between Iraq & Afgan & other places, guys are having to have several weapon systems to accomidate for each AOR. Pain in the ASS, both operationally and logistically. Now, possibly use same lower & grab whatever upper config you need based upon misssion requirements. Does this mean the guys are carrying less gear...nope. It also doesn't mean they're carring more. Those of you picturing guys running around with 5 different uppers in a backpack are unrealistic. What it could mean is that units wouldn't need several guns for each shooter. 1 lower with several uppers (depending on unit needs). No need to buy or train with seperate weapon systems, just the necessary uppers. Switching uppers & entire gun (for caliber) has always been used, now we could use 1 lower for all these options. Means less items in armsrooms, less costs to transport, more money can go where needed (whole other conversation).
As I said...interesting.
