The Support Autocannon (SAC) is a stripped-down version of the light Autocannon-5 developed by the NAIS in the 3060s. With almost nothing but the barrel itself and the ammo feeding mechanism left, the weapons weighs a mere 2 tons, which includes 20 shots in the integrated ammo bin. In order to get out the best of this weapon, the scientists added a minimalist targeting computer specifically optimized for the SAC. The result is a high accuracy comparable to the weapons mounted on a 'Mech, even though being fired over iron sight.
SACs are the only wespons a Chimera can mount that have a range and damage potential similar to the Clans' ER medium lasers. However, they have limited ammo supply, are pretty heavy, and may only be mounted in the right or left shoulder slot. The advantage is that it may use special ammunition like the light AC/5, including some nasty stuff such as AP, precision, and incendiary rounds.
Beware, Clanners. A BattleSquad carrying these things can ruin your whole day. ;A

I think I remember that they tried to explain that by pointing out all the additional infrastructure needed to support such a weapon. A 30 mm gatling cannon like the one in the A-10 weighs less than a ton, and yet it's bullets can shred through almost 100 mm of RHA steel - that would be the samage of an AC/10!
now what is the lightest autocannon/10 weight again? =P

LB-10 X: 11 tons (IS) or 10 tons (Clan).
If you would apply the BA scaling like I did on this one you'd get an AC/10 for a reasonable 2 tons, without ammo.
FYI: battle armor scaled weapons have just 20 percent of their original mass. Energy weapons also need enough heat sinks to dissipate all their heat, and each heat sink weighs 100 kg. Finally, Inner Sphere missile launcher tubes have less than 20 % of their original weight (to make them at least somewhat competitive to their clan counterparts) but the price is that they are too fragine to be used on BA that wants to mount jump jets, aka BA from the inner sphere may not use jump jets until the missile tubes are detached.

Hmmn...About the only thing I can come up with to explain the weight but relative lack of criticals is a shitload of shock absorbers or armored ammo feeds...and that doesn't fully account for the mass given how fragile weapons tend to be without the armor of the 'Mech intact.
Not to mention that armor and internal structure tend to be lighter than they by all rights out to be. I suppose it worked out that way on paper to keep a 20 'Mech from running around with an AC/20. *sigh* I'll find a way anyhow.

Ever considered using some of the rules for your benefit to create a handhelt AC/20 fired over iron sight? ^_~
Weapon weight: 14 tons : 5 == 2.8 tons
Ammo weight for 5 shots: 1 ton
=> 3.8 tons for the weapon itself, and if you go for the extended support vehicle construction rules about maximum heat efficiency (ie no heat generated by ballistic weapons, which would fit here since the fumes may leave the weapon without a 'Mech being in their way) you could have something like a HUGE 'Mech revolver with six shots for a puny little 4 tons. =D

Of course, it would have a few drawbacks. According to the standard rules, a heavy support weapon (when mounted on an IndustrialMech or support vehicle) without being tied to any kind of targeting system receives a +2 penalty. Also, it couldn't be reloaded, unless you use the enhanced actuator system on your 'Mech, which gives 'Mechs the needed dexterity to reload single shells into the chambers. Also, the weapon would be very vulnerable and could explode on the very first hit (if it was critical).
