To be honest the only thing I found wrong with them was their script for re-loading. It bugged constantly.
The AK did 10 damage, fired slowly, inaccurate.
The M16 did 10 damage, fired fast, very accurate.
Both snipers did 100 damage, but when shot quickly, did less damage and became incredibly inaccurate.
The mac11 did more damage then both the ARs.
The Uzi did considerbly less damage then the ARs.
