I cant speak for Koraynovich Arms but from what i heard the other day, AF is expecting more RJ Underfolders in July. I wouldnt hold my breath though
I've done a bunch of searches on these guys and the total lack of info
seems a little suspect to me. I think I am going to wait for the Red Jacket.
I have a Koraynovich Polish underfolder, purchased through Atlantic Firearms back in April. It is a very well built gun. Koraynovich is a small firm currently building guns for Atlantic Firearms, they tend to sell out quickly. I am very happy with this underfolder and would purchase again in a heartbeat. I put up pictures and a short review on the AKFiles.com website.
