I actually just received one of these exact hand guards, and have been using it on my AUG a3 m1. The short version is I really like it. It fits flush with the lines of the gun and feels rock solid once everything is tightened down. It installs with a crush pin through the old hand grip mount point, and then has a pair of screws that clamps the split back half of the hand guard around the gas block. Its super comfortable to hold, especially with an AFG 2 installed.
Only two real issues with it that I've seen so far. First is that it does get unpleasantly hot after 100 or so rounds if you mag dump, but if you are taking your time with aimed groupings it's fine. You could also use some rail covers and grip tape to cover the sections your hand comes in contact with, which is what I plan to do. The second is that there isn't a ton of rail space, especially on the side with the gas piston since the heat cover uses up one of only two available mlok slots on that side. Most of the other slots are all right under where your fingers rest when gripping the hand guard, so there's not a ton of available rails if you have more than a couple things you want to install.
Overall though, its a sleek and comfortable handguard that I think does it's job well.
The importation process surprisingly wasn't all that hard, just time consuming. You need find someone willing to ship to the US who is in the EU, since they are the only people the manufacturer will ship to. Then, you need to use their contact info to file for an ATF form 6, which took about 2 weeks to get approved with efile. Only major hiccup I had was that none of the resellers I could find were willing to ship to the US, so I had the use a packaging forwarding service.
If anyone has questions about the hand guard or the import process I'd be happy to answer them, but I'm limited to 2000 characters for my first post.
