They did quite a few updates/changes. Non-reciprocating, left side charging handle with a rubber dust boot. Ejection port dust cover that reciprocates with the bolt carrier. Latching retention mechanism for the bolt carrier and recoil springs so it doesn't all sproing out when you tilt the upper up and off the lower. Looks pretty cool. Would like to see them build a variant with a longer 18 or 20" barrel eventually.
