Compare the MG RX-75 Guntank and MG RX-77 Guncannon Master Grade kits: design, articulation, build experience, and value for collectors.
When it comes to classic Mobile Suit Gundam kits, the Master Grade (MG) line offers some of the most detailed and satisfying builds. Among the iconic mobile suits from the original series, the RX-75 Guntank and RX-77 Guncannon hold special places in the hearts of fans. Both are support-type units that contrast sharply with the more agile RX-78-2 Gundam, and their MG versions bring these designs to life with modern engineering.
But which one should you add to your collection? In this comparison, we'll pit the MG Guntank against the MG Guncannon, examining their design, articulation, build experience, and overall value. Whether you're a seasoned builder or a newcomer, this guide will help you decide which classic MG deserves a spot on your shelf.
Design and Aesthetics: Tanks vs Cannons
The MG RX-75 Guntank is a unique beast. Unlike most humanoid mobile suits, the Guntank features tank treads instead of legs, giving it a distinct silhouette that stands out in any collection. The MG version faithfully reproduces the anime's proportions, with a bulky torso, twin cannons on the shoulders, and a cockpit hatch that opens to reveal the pilot. Its design emphasizes functionality over grace, making it a favorite for those who appreciate military-style mecha.

In contrast, the MG RX-77 Guncannon is a more traditional humanoid design, albeit with a heavy artillery focus. It features arm-mounted cannons, a shoulder cannon, and a distinctive head with a visor. The MG kit captures the Guncannon's robust frame and adds surface detail that enhances its mechanical realism. While it may not be as unconventional as the Guntank, the Guncannon's design is arguably more versatile, allowing for dynamic poses despite its bulk.
- The Guntank's treads are a unique feature that no other MG kit offers.
- The Guncannon's arm cannons can be posed for dramatic firing stances.
Articulation and Posability
Articulation is a key factor for many Gunpla builders. The MG Guntank, by nature of its design, has limited articulation. Its treads are static, and the upper body can rotate and pivot, but the lack of legs means you won't be doing any dynamic action poses. However, the kit does include a clever mechanism that allows the treads to move, albeit manually. This makes it more of a display piece than a playable figure.
The MG Guncannon, on the other hand, offers better articulation. Its legs feature multiple joints, allowing for kneeling and standing poses. The arms have a good range of motion, and the shoulder cannon can be raised and lowered. While it's not as agile as a Gundam, the Guncannon can achieve a variety of combat stances, making it more engaging for those who like to pose their kits.
- If you value posability, the Guncannon is the clear winner.
- The Guntank's static treads are compensated by its unique display presence.
Build Experience and Complexity
Both kits are from the early MG line, but they offer different build experiences. The MG Guntank is relatively straightforward, with fewer parts and a simpler inner frame. The most intricate part is the tread assembly, which requires careful alignment. This makes it a good choice for beginners or those looking for a relaxing build.
The MG Guncannon is slightly more complex, with more parts and a more detailed inner frame. The arm cannons and shoulder cannon add to the build time, but the result is a more satisfying sense of accomplishment. For experienced builders, the Guncannon offers more opportunities for customization, such as adding panel lines or painting.
- The Guntank's treads can be a bit fiddly but are manageable.
- The Guncannon's inner frame is a great base for detailing.
Accessories and Extras
When it comes to accessories, the MG Guntank is fairly minimal. It includes its signature cannons and a few optional hands, but there's not much else. This might be a downside for those who enjoy extra weapons or effect parts.
The MG Guncannon, however, comes with a bit more. It includes its arm cannons, a shoulder cannon, and a few hands, but also features a unique gimmick: the core fighter. Yes, the Guncannon can incorporate the core block system, allowing you to display the cockpit separately. This adds an extra layer of playability and display options that the Guntank lacks.
- The Guncannon's core fighter is a nice bonus for collectors.
- If you're into effect parts, consider pairing the Guncannon with the 30MM Customize Effect 06 (Slash Image Ver.) [Blue] for dynamic action scenes.

Price and Value
Price is always a consideration. The MG Guntank tends to be slightly cheaper than the MG Guncannon, reflecting its simpler design and fewer parts. However, the Guntank's uniqueness might justify its price for collectors who want something different.
The MG Guncannon, while a bit pricier, offers more features and articulation, making it a better value for those who want a more interactive kit. Additionally, both kits can be enhanced with aftermarket accessories like the Mr. Waterproof Sand Paper #2000 MT309 for smoothing nub marks, or the Gaia 003 Gloss Bright Red for painting details.
- Check your local retailer for current pricing, as both kits are widely available.
- Consider investing in quality tools like the Mr. Waterproof Sand Paper #2000 MT309 to improve your build finish.
In the end, the choice between the MG Guntank and MG Guncannon comes down to your personal preferences. If you want a unique display piece that stands out from the crowd, the MG Guntank is a great choice. If you prefer a more articulated and feature-rich kit, the MG Guncannon is the way to go. Both are excellent representations of classic mobile suits, and either will be a worthy addition to your Master Grade collection.
