The Gunslinger is a product of the Clan Invasion and would not exist if not for that violent conflict. The 'Mech was jointly designed by engineers from both the Draconis Combine and the Federated Commonwealth who were in the process of assisting the Free Rasalhague Republic. To power the Gunslinger, a VOX 255 XL engine is used to give the 'Mech a top speed of 54 km/h. This is augmented by a pair of HildCo Model 12 jump jets that allow the Gunslinger to traverse rough terrain and provide extra mobility at close ranges. The 'Mech is also equipped with a Guardian ECM Suite and a Beagle Active Probe, giving the Gunslinger superior detection capabilities and protection from advanced enemy electronic warfare equipment. Finally, the Gunslinger is protected by fifteen and a half tons of armor, giving the 'Mech excellent armor protection.

Weapons and Equipment[edit]

The Gunslinger carries as its primary weapons two arm-mounted Poland Main Model A Gauss rifles that can each strip off a ton of armor at ranges of over six hundred meters. As the Gunslinger closes with the enemy it is able to bring to bear its four Defiance B3M medium lasers and a Defiance A5L Small Laser that help to make up for the ineffectiveness of the Gauss rifles at extremely short ranges. Finally, to protect against attacks on its weak rear armor, the Gunslinger carries two rear-mounted Defiance P5M Medium Pulse Lasers.


  • GUN-2ERD 
    The 2ERD model of the Gunslinger upgrades the medium lasers to ER medium lasers and removes the two rear Medium Pulse Lasers, the Beagle Probe and the Small Laser. The 'Mech then adds an additional jump jet allowing the 'Mech to jump up to ninety meters and also adds a C3 master computer.[1] BV (1.0) = 2,135, BV (2.0) = 2,423[5]
  • GUN-3ERD 
    A Dark Age Era variant introduced in 3131 by the Draconis Combine, this version of the Gunslinger uses a mix of Clan and Inner Sphere technologies. Powered by a 225-rated Clan XL Fusion Engine, the 'Mech retains the speed and limited Jump Jet capacity of the original, while the gyro is replaced by an XL version. Weapons-wise, its primary weapons remain its arm mounted Gauss rifles with four tons of ammunition. The four Medium Lasers in the side torsos are replaced by Clan ER Medium Lasers, while three X-Pulse Small Lasers are fitted in the head, with the remaining two rear-mounted on its legs, replacing the original two Medium Pulse Lasers. Protecting its hull is Ballistic-Reinforced Armor. To fit the necessary armor, it removed the Guardian ECM, Beagle Active Probe, and one ton of ammunition from the original design. [7]
