Oh yeah the 416 is really good. Me and a buddy have the 416 as our main rifle, we also have the M27 and that is a beast.
Here is where I bought my HK416 https://modernairsoft.com/collections/gun-finder-ar-hk-416
I would wait for the new one to come out. It will be released in the next month or so. But overall there a great product. We will have them at East Coast Airsoft when they come out. The older version has been discontinued in America for almost a year now.
Really? Will they release a 416-C in the Avalon internals?
I don't think a C will be out with the first batch. This is the only "official" info they have posted. But my sales rep said they should be coming out within a month. But I have not heard any info on any other colors or models yet.
