I know that in 2006 the Army National Guard bought over 30,000 of them at $3,000 a piece. That being said, you definitely can't go to Cabela's and buy one but my guess would be in the $10,000-$15,000 dollar range, given the nature of the weapon and it's legal status.
The M249 Squad Automatic Weapon fires the same 5.56x45mm cartridge used by the M16 and M4.
The maximum effective range of the M249 light machine gun is 1,000 yards (910 meters).

Technically the PKM, since it is an AK-47 variant it fires a 7.62mm round while the M249 shoots a smaller 5.56mm round
700-1200 rpm.
In short the M249 is effective up to 1000 meters to cover an area target which the gun is designed to do.

The M249 is not a rifle - it is a light/general purpose machine gun, also commonly referred to as a SAW (Squad Automatic Weapon). Informally, it's sometimes referred to as the 'piglet'.

M249 SAW or MLG is used in Battlefield. This game is a US version of Belgian-Made FN Minimi. It uses the 5.56x45mm NATO round, which lowers the weight of the gun.
