Advanced Gun System
   First built in the Twin Sons system of the Free Worlds League the advanced gun system was a high-tech variant of the Hand-Held Gun already employed by many of their Ultra-Light Mechs.  Designed for larger BattleMechs to allow them to bring an extra weapon to a fight.  These weapons were not designed to be long live affairs but instead an entry level piece of firepower which could be discarded and recovered once the battle was done.

Any weapon mounted on the AGS weighs half as much as a standard weapon system but any AGS can only carry a single weapon, with ammunition, heat sinks or armour.  The AGS is harder to use than standard weapons, so they require additional fire control to help guide the munitions to their target even paying this Fire Control tonnage the weapon has a +1 modifier to hit.  Without the fire control the weapons have a +3 to hit modifier.

Rules
Single Weapon system may be mounted at any time
Ammunition, Heat Sinks and Armour added as standard
Weight then halved once all have been added
For every ten tons of weapon 1 ton of fire control must be paid any weapon built without fire control will gain +3 to hit

Example
Autocannon/10 Advanced Gun System
Autocannon/10          + 12 tons
Ammo AC/10 (10 Rounds)   + 1 ton
Fire Control         + 1.5 tons
Armour (8 Points)      + 0.5 tons
Total AGS Weight/2       = 7.5 tons

Advanced Rules
Only one weapon (1 item, not type) may be included in any AGS
+1 Penalty to hit when using the weapon
BattleMech must have two functioning hand actuators to use the weapon otherwise it cannot be used.
