Here is a few facts:
1. The AK47 when in FPS is a AK74 design, while on the ground, it look like the AK47.
2. The AK47 should not be able to miss people a lot, the AK47 should be able to hit a target over 250-300 yards.
3. The M40 sniper rifle have a caliber that should kill anyone with one hit.
4. The SVD should be very hard to shoot in CQC
5. The SCAR suffers from sand problems, thus should be useless in sandy maps.
6. The Uzi does not have a huge rate of fire.
7. The UMP 45. should be more hard hitting.
8. The M16A3 is acutally the M16A2, the A3 does not have automatic, just burst.
Now I will shut up. :/
Nexon made a lot of weapon flaws. :/
