A little more $$$...but I love the looks of the VEPR Hunter.
For a shotgun...why not a Saiga?
For a 22lr...
You could buy a Ruger Mark or 22/45 and a suppressor.
I like the Mark series better because its all metal, but the 22/45 accepts 1911 grips, and can come with a threaded barrel with rails on top and bottom from the factory.
How awesome would it be to have a suppressed 22lr pistol? You could also afford a suppressed 10/22 if you'd prefer the rifle.
You could probably also afford to buy a 22 rifle plus a suppressor for your UZI or maybe SBR it.
Since you like AKs...
