I sold mine a while ago. Great gun, but I had the following concerns.
1) on mine, the rear of the receiver was solid, similar to an under folder, so it would not accept a standard stock. Only one of the thumbhole stocks. Mags were also really sloppy fit.
2) it was made from a milled parts kit. There were a few people who ended up with cracked front trunions. Since these were made from milled kits, there was questions on where the front trunion came from.
That said, mine had the best trigger I have ever seen on an AK. It was a double hook. It would not feed hollow points more than twice in a row. It also had the thicker 1.6 mm receiver and heavy chrome lined barrel.
