|Could experienced users of both weapons rate the reliability, effectiveness(penetration) and accuracy of both 7.62mm weapons? I have always felt that both these weapons are very similar even in looks, reliability, and are suitable for vehicle mounts. Obvious differences are that the PKM seems to be lighter by a kg or 2, and that FN MAG uses center fire ammo, while the PKM soldiers on with a 100 yr plus rimmed cartridge. (that does not seem to affect reliability)
PKM also has a slightly longer barrel despite lighter weight.
The views that I observed were that US troops rated the FN240 as their top favourite MG, but that the PKM issued to Iraqi soldiers are also pretty good. I hope u guys could give me a more informative reply.
