The RGM-79SC GM Sniper Custom is a variant of the mass production RGM-79 GM and was first featured in the original design series Mobile Suit Variations (MSV).

Technology & Combat Characteristics[]

Unsatisfied with the performance of the RGM-79 GM, a number of Federation ace pilots requested an improved version of the mobile suit. As a result, two modified GM variants were produced: the RGM-79L GM Light Armor and the GM Sniper Custom.[1] Despite its name, the GM Sniper Custom was a general-purpose unit capable of long-range sniping, medium-range support, and close-range combat.[2]

Compared to the base GM, the GM sniper Custom featured more powerful thrusters on its backpack, which rivalled the RX-77-2 Guncannon in terms of output; additional high-output thrusters on the back of the leg; a pair of powerful cooling units were mounted on the waist armor, allowing stable operation in situations that would otherwise be overtaxing; and an additional armored visor, equipped with an original image sensor and dedicated enhancer, was fitted on its head. Although this visor was meant only for protecting the dual camera eyes during close range combat, it could exhibit extremely high precision when used with the R-4 Type Beam Rifle.[1][2]

Thanks to its various improvements, the GM Sniper Custom's performance rivalled that of the RX-78-2 Gundam.[1] This proved that even mass production mobile suits could become high-spec machines through fine-tuning.[2] However, due to cost issues, fewer than 50 GM Sniper Customs were produced.[1][2] Later, the GM Sniper Custom served as the base unit for two other specialized variants: the RGM-79KC GM Intercept Custom and the RGM-79HC GM Guard Custom.[1][3]


  • Box-type Beam Saber Unit[4]
A box-shaped device mounted on the right forearm capable of emitting a beam blade. The beam saber within the box can be taken out and used as a handheld weapon.[2]
  • R-4 Type Beam Rifle[5]
Model number: BR-M79-L3[6][7]
A beam rifle designed specifically for the GM Sniper Custom, range and output have been increased, but it has a smaller ammo capacity.[8] When used by the GM Sniper Custom, its effective range greatly exceeds the range of the RX-78-2 Gundam's beam rifle.[2] It shares the same frame structure as the standard beam spray gun.[6] The rifle's barrel, stock, and scope can be folded when not in use.[2]
  • L-3 Sniper Beam Rifle[9]
Model number: BOWA BR-S-85-L3[10]
A type of beam rifle which became the standard weapon of the GM Sniper Custom during the Gryps Conflict, it used the same sensor as the RMS-179 GM II's beam rifle.[11] One such rifle was used by Federation ace pilot Tenneth A. Jung's GM Sniper Custom during the One Year War.[9] This hints that it might have been a predecessor to the GM II's beam rifle.
  • BOWA BR-M-79C-1 Beam Spray Gun
A standard beam spray gun could be stored on a storage rack on the calf of the machine. The beam spray gun featured three fire modes: a basic single shot mode, an area suppression burst shot with a widened beam focus, and a range shot with the ability to cause damage over a wide area. Output 1.4 MW.
  • BOWA XBR-M-79W-2 Twin Beam Gun
A double-barreled version of the BR-M-79C-1 Beam Spray Gun. This design suppresses barrel heating by firing alternately from the two barrels.
  • BOWA XBR-S-79b Folding Beam Handgun
A secondary beam sidearm stored on the side skirt armor or on the inner side of the forearm via a bracket, its grip can be folded up during storage.
  • BLASH HB-L-03/N-STD Hyper Bazooka
A general purpose fire support rocket launcher platform for mobile suits. With considerable destructive power owing to the high explosive yield in each warhead, the weapon was primarily used to destroy less maneuverable targets such as warships, satellites, land battleships, bunkers, and buildings. The weapon was ultimately used with four main types of rounds: a space-use dual stage booster-equipped HEAT (High Explosive Anti-Tank) round, an APFSDS (Armor Piercing Fin Stabilized Discarding Sabot), a HESH (High Explosive Squash Head) as well as a shotgun-type round.
  • FADEGEL RGM-M-Sh-007 Shield
The same shield as used by the RGM-79C GM Type C, it is an improved model of the RGM-M-Sh-003. It has the exact same size as its predecessor, but its material was changed to Titanium-Ceramic composite. Its mount latch was made movable, allowing the shield to be positioned up or down when carried by a Mobile Suit manipulator or mounted on the forearm, increasing its usability.
  • RGM*S-Sh-WF/S-00109 Shield
Mounted on the forearm, this small, light shield is commonly used by the Gundam Ground Type and GM Ground Type. Constructed of Luna Titanium alloy, it is designed to primarily protect the cockpit and other critical areas. Additionally, it can be used as a close-range striking weapon in mobile suit combat. Furthermore, through lodging the spikes at the tip into the ground, the shield can serve as a free-standing frontal defense. This also allows the mobile suit to use both hands to hold large-caliber weaponry and maintain a stable firing position. Only used by Gundam Fix Figuration version.


After the Battle of Solomon, modification of the RGM-79 into the RGM-79SC GM Sniper Custom took place at the newly captured Solomon and Luna II.[12] 24 early production units were produced by Luna II as part of the third production run.[13] In total, less than 50 GM Sniper Customs were constructed due to cost issues.[1] These units often had various customizations applied to them by their pilot.[14] The unit piloted by Lieutenant Francis Backmeyer was said to be the most heavily armed, and roughly half of all units imitated his loadout.[1] Tenneth A. Jung, the Federation's top ace pilot during the One Year War, also piloted a GM Sniper Custom.[15]

The GM Sniper Customs were mostly assigned to escort fleets and defend transport ships in dangerous space sectors. A small number was assigned to special forces units to carry out sabotage and surprise attacks on Zeon forces stationed at each Side. Pleased with the Sniper Custom's performance, the EFSF headquarters ordered the development of an improved version for the attack on the Zeon homeland, which eventually became the RGM-79SP GM Sniper II.[16] Later, a large number of GM Sniper Custom and its variants participated in the Battle of A Baoa Qu,[17] including Francis Backmeyer's unit.[2]

In Mobile Suit Gundam 0083 Rebellion, a GM Sniper Custom belonging to the 404th airborne unit provided sniper support to a team of RGM-79V GM Night Seeker in capturing the stolen RX-78GP02A Gundam "Physalis". It was fixed to an Assault Type Gunperry and destroyed a MS-05L Zaku I Sniper Type defending the Komusai II transporting the Gundam. However, due to dense fog and the destruction of the GM Night Seeker team, it was forced to retreat.

In U.C 0087, several retrofitted GM Sniper Customs were used during the Gryps Conflict and deployed at Jaburo.[11] They were equipped with the same leg suspension system and linear seat as the RMS-179 GM II.[1]

Mobile Suit Gundam F90: Fastest Formula[]

In U.C. 110s, a customized GM Sniper Custom, the RGM-79SC GM Sniper Custom (GBG Specifications), was used by a mercenary group called Gleam Black Guns (GBG) as one of their sniper units. It was piloted by Dill Rider, who was actually Liv Angelika in disguise after he was supposedly killed during an earlier incident. For almost three years, the GM Sniper Custom (GBG Specifications) fought together with the GBG's customized GM IIIs.

In U.C 115, the GM Sniper Custom (GBG Specifications), the RGM-86R-FA Full Armor GM III, and the RGM-86RN GM III Euryale was on mission to eliminate a Zeon remnant group called "Legacy". This mission was later revealed to be an ambush set by Legacy to test their newest MS, the OMS-1004 Tigris II. A fierce battle erupted between the GBG team and around a dozen Tigris IIs, ending with the GM Sniper Custom (GBG Specifications) being the sole survivor.[18]


Featured in Mobile Suit Gundam F90: Fastest Formula, this machine was used by the Gleam Black Guns (GBG) mercenary group as their sniper unit. The GM Sniper Custom (GBG Specifications) was modified using contemporary MS parts, enabling it to achieve comparable performance as the EFF's latest miniaturized MS, the RGM-109 Heavygun. The unit's loadout did not differ much from the original, but it had customized weapons to fit Dill Rider's combat style, such as the addition of missile launcher on the left shoulder, beam pistol, and extra beam saber.[18]
