RGM-79SC GM Sniper Custom

The RGM-79SC GM Sniper Custom is an Earth Federation mobile suit from the Mobile Suit Variation line. It is an upgraded ace-use version of the RGM-79 GM, developed during the One Year War for pilots who needed better performance than the standard mass-production GM.

Despite the “Sniper” name, the GM Sniper Custom is not only a long-range unit. It has improved generator output, sensors, thrusters and armour, allowing it to handle a wider range of weapons and battlefield roles. It can use precision rifles, beam rifles, beam sabres, shields and other Federation equipment depending on depiction. The head visor and additional armour details distinguish it from the simpler standard GM.

The machine is associated with the MSV tradition of expanding the original Gundam setting through ace machines and specialised variants. It sits alongside other GM derivatives such as the GM Cannon, GM Light Armor and later GM Sniper II, showing how the Federation reused the basic GM frame for higher-spec pilots and specific mission needs.
