Do a google search of walnut hollow country turkey mount
They make nice real wood ones
I ordered mine from them on amazon as it was cheaper on there for some reason
They make ones without the picture on it if that's your style
Bushmasters are not bad I have shot a couple and they work just fine. Just think of it as a chevy Malibu. Yes there are Camaros and Corvettes out there but they come with a price. If you are just needing to get to work and back the Malibu is just fine if you want to go to the track the corvette is better.
I am getting the drift he wants the gun in case you know what hits the fan well in that case the bush master will do. If he wants to do some serious shooting or competition 3 gun or whatever I would suggest otherwise.
As far as the wall penetrating debate Its all hog wash unless you are hitting studs the bullet is going through drywall with the exception of birdshot will stop after a wall or two
The importation of AKs was banned during the Obama administration, but there were a lot of them imported prior to the ban, so they are still available. Probably not at big box stores, though. You would have to shop around, and some of them bring high prices due to the mods made to them.
