The one I had was pretty simple and straightforward to put together.
Although, in fairness, I thought the long barrel with front sight post looked a little wrong. So, I took it off, shortened the barrel to the legal limit. And threaded it.
Mag changes sucked though. I never could get the hang of it, and ended up selling it to a buddy who just had to have it.
FWIW, Jesse James Firearms had one on their website once a long time ago. He must've been really proud of it, considering the cheap $30 tasco 50mm red dot and the crazy sticker shock that he thinks he's owed because he touched it. I'm thinking it was around $850 (this when SKS were selling for $200). The stock was selling for about the same. So, whoever bought it, doubled his money.
