100.000-500.000
Depends on which make, and what version. Typically $400-$600.
In semi-auto they can be found for as low as $350, but the full-auto cost much more around $13,000 after you get your class III licence to own one.
I have read around that a used AK-47 can be purchased with less than 30 USD in some african countries

About 123 grains.

Your question is sort of like "How much does a car cost?" Depends on the car, and depends on the rifle. If you mean a civilian version (semi auto) of an AK47, about $400. If you mean a legal, select fire (semi or full auto) M16, about $16,000 plus fees.
a chinese is the bottom price at 3.50$ a russian is the most expensive into 1.000$ these arent fully automatic though and anything added to them for looks or preformence raises the price
ciener inc. currently has them for sale for $200
