bang bang bang!
Now that the "AW ban" has sunset (and we're going to make sure it stays that way, right? $;-), I look forward to the civilian semi-auto version of this hitting the market in the next couple of years. The HK reps at the last SHOT show said that HK is ready, willing and able to produce these for the civilian market. The domestic production facility is part of that plan.
As for .223 or 6.8 SPC versions, they have both in proto, although the .223 is further along. I expect to see both, again, at least for the civvie market.
