I've been keeping an eye out on the Arsenal SAM7K -44 since last year when the new changes made it easier to add a 4 Piece Booster from the factory (Bulgarian 4 Piece from KVar attached).
I also added the Krinkov flashlight which takes two CR123A batteries to it. It has only one switch on the right side with an easy to press for momentary on and a more difficult and deeper push for constant on/off.
The CNC Warrior right side folding brace is a beast. Just like the one I have for my AES-10B. It was an easy install and the video was very helpful.

The brace is pretty thick, close at it's two thickest points to my East German side folder. It's quite comfortable and I enjoy the shorter length of pull (13" trigger to shouldering).
With the stock folded, the charging handle can move freely. You could fire the gun with the stock folded as a right handed shooter but the stock does get in the way of the trigger finger some (it's uncomfortable).
Overall, the gun is very smooth and well put together. I'm looking forward to shooting it at the range this weekend with some SGAmmo's range safe rounds.
