I just picked up one of these for $599 from Classic and so far I am really impressed with the quality, fit and feel. I have been looking online for more information but have not been able to find much. Most is from Euro and Canadian websites. Its made by the Turkish company Hunt Group and goes by different names but its always FD12. Cosmetically I dont care for the fake keymod but other than that the thing is very solid and well built. Well balanced and very compact. I havent had a chance to shoot it yet but all of the reviews I have seen say it eats low and high and is very reliable. I will update once I have a chance to take her shooting but was curious if anyone else has experience with them. It handles 3" and uses Beretta/Benelli chokes. I was trying to find a good choke/brake and possibly add a K grip as it looks like it uses AR grips.
I also love the fact that the manufacturer posted this video on their own website.

Also, it works well with the Promag 20 and the MKA 1919 mags.
