Technology & Combat Characteristics
A variant of the GAT-01A1 Dagger (aka 105 Dagger) piloted by the "Moonlight Mad Dog", Morgan Chevalier. The Gunbarrel Dagger mounts the AQM/E-X04 Gunbarrel Striker as a Striker Pack, granting the suit usage of the remote controlled Wired Gunbarrels (which could only be controlled by individuals with high spatial awareness, like Morgan) and perhaps the Striker's Gatling gun, in addition to the Dagger's standard weaponry. The Gunbarrel Striker can be automated or piloted, and if it is the latter, the front section can be detached after the Striker Pack docks to the Dagger's back, which make sense as the unit's pilot is useless after the pack docks with the MS. In fact, this is what Morgan often does if the pack is delivered in battle by a pilot. As the wires of the wired gunbarrels can be easily severed during combat, a backup Gunbarrel Striker is always prepared in advance and send out when almost all the wired gunbarrels have been severed or destroyed.
History
Originally, the plan for Gunbarrel Striker was to equipped it onto the GAT-X105 Strike Gundam that was stationed on the Archangel. The resulting GAT-X105+AQM/E-X04 Gunbarrel Strike Gundam was meant to be Mu La Flaga's personal unit, but as the plan did not materialize due to Mu's defection. The Gunbarrel Striker was passed on to "Moonlight Mad Dog" Morgan Chevalier, who also has high spatial awareness, for use with his 105 Dagger.
Morgan used the Gunbarrel Dagger in many battles during the First Alliance-PLANT War. In one such battle, he fought against the CAT1-X1/3 Hyperion Gundam Unit 1 piloted by Canard Pars at the Ptolemaeus Lunar Base, when Canard attacked the base to obtain a Neutron Jammer Canceller. He only survived this battle because of Prayer Reverie psychically urging him to detach his Gunbarrel Striker. Later, Morgan and his Gunbarrel Dagger participated in the Battle of Boaz, during which he led a large force of Strike Daggers to clear the way for the Peacemaker Force's nuclear missile-equipped TS-MA2 Moebius units. In the final battle of the war, the Second Battle of Jachin Due, Morgan and his Gunbarrel Dagger led a squad of seven other 105 Daggers (equipped with the Aile, Sword, and Launcher Striker packs) against a ZGMF-1017M GINN High Maneuver Type squad led by Mikhail "Doctor" Coast and also fought a YFX-600R GuAIZ Experimental Firearms Type, piloted by Heine Westenfluss.
After the war, Morgan piloted his Gunbarrel Dagger against rogue Alliance ace and South American revolutionary Edward "Ed the Ripper" Harrelson. Following a brief battle, Morgan used the wires of the wired gunbarrels to immobilize Ed's GAT-333 Raider Full Spec and forced it deep into Earth's gravity well. Morgan, however, declined to take a killing shot and instead gave the "Hero of South America" the opportunity to prove himself by surviving the seemingly impossible situation, which Ed eventually did. During the Second Alliance-PLANT War, Morgan moved on from the Gunbarrel Dagger to the TS-MA4F Exus mobile armor.
