Master Grade is the heart and soul of serious Gunpla building. Launched in the summer of 1995 to mark the 15th anniversary of Gundam, MG set a new standard for what a model kit could be. 

At 1/100 scale, these kits stand around 18 to 22 centimeters tall depending on the mobile suit, and they deliver a level of detail, articulation and proportions that is second only to Perfect Grade. The defining feature of gunpla master grade is the skeletal inner frame. You build the entire skeleton of the mobile suit first, piece by piece, constructing a fully functional mechanical body with working hydraulic pistons, layered joint mechanisms, moving armor sliders and exposed internal components. Then you add the armor panels on top, covering the frame section by section and giving the kit its final form. That two stage build process is what makes MG so deeply satisfying. You are not just assembling a model. You are building a machine from the inside out, and at every step you can see and appreciate the engineering underneath. 

Many MG kits accommodate Bandai's Gunpla LED Units, usually sold separately, which slot into the head, chest reactor or thruster sections to produce light up effects. Most kits also come with 1/100 scale pilot figurines, both standing and seated, so you get a true sense of the mobile suit's size relative to a human being. Some kits even include 1/20 scale character figures for cockpit display. 

From 1995 to 1998, the earliest MG releases also included "heavyuser" parts: optional detail pieces that could be cemented to armor panels with glue for added surface texture and mechanical depth. It was a feature that showed Bandai's ambition to push the grade toward something truly premium from the very beginning. 

Over the decades the line has gone through continuous evolution. Starting in 2005 with the Zeta Gundam and Gundam Mk-II, older kits began receiving full redesigns under the Ver.2.0 moniker, bringing improved articulation, full inner frames (some early MGs had partial frames) and modern proportions. The RX-78-2 alone has had more MG versions than any other suit: Ver.1.0, Ver.1.5, Ver.Ka, Ver.OYW, Ver.2.0 and Ver.3.0, each reflecting the state of Bandai's engineering at the time of release. 

The Ver.3.0, released in 2014 for the Gundam 35th anniversary, incorporated techniques from both the MG 2.0 system and Real Grade kits, and was inspired by the 1/1 scale RX-78-2 statue at Odaiba. Other redesign labels include Ver.RM (Remaster) and Ver.3.0, each targeting different suits that deserved an update to modern standards. A typical MG build includes 300 to 600 parts depending on the kit and takes around 6 to 12 hours of assembly time for a straight build out of the box. 

For builders who paint, add panel lining, apply waterslide decals and weather the finish, a single Master Grade project can stretch across weeks or even months. The gunpla mg catalog is enormous, covering suits from Mobile Suit Gundam, Gundam Wing, Gundam SEED, Gundam Unicorn, Gundam 00, Thunderbolt, Iron-Blooded Orphans, GQuuuuuuX and many more. The line has even hosted mecha from outside the Gundam franchise, including Aura Battler Dunbine and Mobile Police Patlabor. We hold one of the largest MG selections in real stock in Europe, with kits sitting on our shelves in Barcelona ready to ship immediately. No waiting on back-orders. No virtual inventory. If you want the full Gunpla experience at a scale that shows off every detail, Master Grade is where you belong.
