oh i can think of other cons as well
1. x39mm ammo not very accurate beyond 200yrds, maybe 300 .... in virtually any gun
2. ammo is very dirty and below our 5.56 standards certainly
3. any advantage gained in loading a tapered round is probably pointless when you consider mud/dirt can also get into an AR's locking lugs.
4. bullet energy is lost in shorter distances than most
gotta admit that AK arguement's looking better and better
then just outfit the designated marksmen with ar-10
