If you are asking about full-auto I would say at least $10,000 or more. Semi auto models about $1500.00 to $2000.00 right now.
Depending on the maker it will run between 800-1400 dollars on average.
The M16 sieries of rifles are individual combat weapons.
the M16 assault rifle is composed of steel, aircraft grade aluminum, composite plastics, and polymer
Depends where you are and what gun regulations are in place.
M16
A M16 cost about $2000.00
No such weapon.
No such weapon made by Colt

it would cost about 850 dollars and if you want an airsoft one that looks exactly like a real one it would cost about 50 dollars.
That really depends on the brand and who is selling it. A Colt Defense -the original producer of the M16- will cost you around 1,400 to 1,600 dollars (or more depending on the specifics). But many other companies produce and sell M16s and their variants for cheaper. I just bought a Stag Arms M4 (the carbine version of an M16) for 800 dollars, and have found other models at gun shows for as low as 500. The best way to truly price an M16 in your area is to find a local gun show and just shop around.
Ducati Desmosedici D16RR NCR M16, is the most expensive ducati motorcycle with a price tag of $232,500.
Most guns are 2000 cod points, the M16, Olimpia, MP5K, dragunov, and HK 42 are free. the crossbow and ballistic knife are 3000.
5.56mm packs a punch. It's stopping power is good, but a gun like the MG3 can easily outkill an M16 with its 7.62mm rounds.
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.
In a way the M16 is a machine gun, but it can also do three round burst and semi automatic. civilians are not allowed to have automatic m16s unless you have an automatic weapons permit, but you can have a semi automatic M16. (an AR-15 is almost like an M16 and much cheaper if you're looking to buy one.)
8.5 pounds or more depending on how much attachments you put on it.
