Explore the MG RX-75 Guntank in this detailed review. We cover build quality, articulation, and how it compares to other Master Grade kits.
The RX-75 Guntank is one of the most iconic mobile suits from the original Mobile Suit Gundam series, and its Master Grade (MG) incarnation finally gives this classic machine the treatment it deserves. As a non-humanoid mobile suit, the Guntank offers a unique building experience that stands out in any Gunpla collection. In this review, we'll take a close look at the MG RX-75 Guntank, examining its design, build, articulation, and overall value.

Whether you're a seasoned builder or a newcomer to the hobby, the MG Guntank presents a refreshing departure from the typical humanoid kits. Its tank-like lower half and twin cannon arms make it a distinctive addition to any shelf. Let's dive into the details and see if this Master Grade kit lives up to the legacy of the original series.
Overview of the MG RX-75 Guntank
The MG RX-75 Guntank was released as part of Bandai's Master Grade line, which is known for its high level of detail and engineering. This kit captures the bulky, utilitarian design of the Guntank from the original anime, with a mix of plastic colors and some pre-painted parts. The kit features a full inner frame for the lower tracks and a simplified upper body that still offers plenty of mechanical detail.
One of the standout features of this kit is its transformation to the 'Tank Mode' and 'Mobile Suit Mode.' While the Guntank doesn't transform in the traditional sense, the kit allows you to pose the arms and turret in various configurations, mimicking its role as a long-range artillery unit. The included decals and marking stickers add to the authenticity, though some builders may prefer water-slide decals for a cleaner finish.
- Scale: 1/100 Master Grade
- Includes: Inner frame, articulated tracks, twin 120mm cannons, and marking stickers
- Release Date: 2004 (original), with reprints available
Build Experience and Engineering
The build process for the MG Guntank is engaging and well-paced. The lower half is composed of multiple track links that are connected to form the treads, which are surprisingly articulated. The upper torso features a detailed cockpit hatch and a rotating turret. The arms are simple but effective, with the cannons mounted on the forearms. The kit uses a mix of ABS and PS plastic, and some parts require painting for the best appearance, especially the inner frame and small details.
One of the most impressive aspects is the track system. Each track link is individually molded and can be assembled to create a flexible, realistic tread that moves with the wheels. This adds a level of complexity that is rare in Gunpla kits, making the build more rewarding. However, the tracks can be finicky to assemble, so patience is key. Overall, the engineering is solid, and the kit holds together well once completed.
- Track assembly is time-consuming but results in functional treads
- Consider painting the inner frame for a more detailed look
- Use a hobby knife to clean up nubs on the track links for a smoother fit
Articulation and Posability
Given its non-humanoid design, the MG Guntank's articulation is different from typical mobile suits. The lower half features a series of wheels and tracks that allow it to roll forward and backward, but there is no side-to-side movement. The turret can rotate 360 degrees, and the arms can pivot at the shoulders, providing a decent range of motion for aiming the cannons. The cannons themselves can elevate and depress, allowing for dynamic firing poses.
While the Guntank cannot perform the acrobatic poses of a Gundam, its articulation is perfectly suited for its role as an artillery unit. The kit includes a small display stand that can be used to prop up the rear, though the Guntank is stable enough to stand on its own. For those looking to recreate iconic scenes from the anime, the MG Guntank delivers.
- Turret rotates fully, arms pivot at shoulders, cannons elevate
- Tracks roll, allowing for rolling poses
- Comes with a small stand for dynamic display
Comparison with Other Master Grade Kits
When compared to other Master Grade kits, the MG RX-75 Guntank holds its own. While it lacks the intricate inner frame of newer MGs, it offers a unique build that is both challenging and rewarding. The level of surface detail is excellent, with panel lines that are crisp and easy to panel line. The kit also includes a set of dry-transfer decals, which are a nice touch for adding authenticity.
In terms of value, the MG Guntank is reasonably priced for a kit of its size and complexity. It may not have the shelf presence of a large mobile armor, but it certainly stands out among humanoid suits. If you're looking to expand your collection with something different, the MG Guntank is a worthy addition. For those who enjoy customizing, the kit's parts can be easily painted, and the tracks provide a good canvas for weathering techniques.
- Excellent surface detail for panel lining
- Unique build experience compared to humanoid MGs
- Great base for customization and weathering
Accessories and Extras
The MG RX-75 Guntank comes with a modest set of accessories, including the two 120mm cannons, a pair of missile pods (which are not featured in the anime but add to the play value), and a pilot figure of Ryu Jose. The kit also includes a sheet of marking stickers and dry-transfer decals for the various warning signs and unit markings. While the accessories are not extensive, they are sufficient for the Guntank's role.
For those looking to enhance their Guntank further, third-party products like decals and detail-up parts are available. For example, the Delpi Decal RG Zeong - [Gold HOLO] offers a nice holographic effect that could be used to add flair to the Guntank's sensors, though it's designed for the Zeong. Alternatively, you can use the Kustom Service Color Force Yellow 30ml to paint the yellow accents on the chest and shoulders, giving the kit a more vibrant look.
- Includes two 120mm cannons, missile pods, and a pilot figure
- Marking stickers and dry-transfer decals included
- Optional decals and paints can enhance the final look

Its unique design, solid build, and functional tracks make it a standout in the Master Grade line. While it may not have the complexity of some newer kits, it offers a satisfying build that is both fun and challenging.
