Looking them over, Kilo's seems to be over the limit; double railguns, double ACs:
[quote]Right Arm:
37mm Automatic Cannon

Left Arm:
37mm Automatic Cannon or a five foot long Laser Cutter

Shoulders:
Twin 88mm railgun cannons and six 20mm smoke grenade launchers[/quote]

In the cases of melee weapons, I won't count them towards the limit, seeing as they would be used much less and their effectiveness isn't as great as conventional armaments. So things like the pneumatic spike or heat knife are considered add-ons.
Kilo could run her loadout above, so long as the second AC was permanently replaced with the laser cutter.
