Walk into the Gundam plastic model (gunpla) hobby and the first question you hit is which scale to start with: Real Grade (RG) at 1/144 or Master Grade (MG) at 1/100. Bandai sells dozens of grades, but RG and MG are the two that matter for most new builders. They occupy a similar price tier, both deliver impressive detail, and both are widely available on AliExpress in 2026 — sometimes for less than half their suggested retail in Western hobby stores.
This comparison answers the practical question: which scale is the right first kit, and which is the right long-term hobby? Short answer: start with RG. Move to MG once you know you enjoy the build process and want a longer, more detailed project.
Quick verdict
- Buy an RG kit if this is your first or second gunpla, you have a small desk, and you want an impressively detailed model in a single weekend.
- Buy an MG kit if you have already built a couple of HG or RG kits, you have more shelf space, and you want a 10+ hour build with full inner-frame articulation.

Build complexity and assembly experience
The two grades feel very different to build, even though both are snap-fit kits with no glue or paint required.
RG kits use Bandai's Advanced MS Joint system: a pre-assembled inner skeleton that you snap armor pieces onto. The skeleton already has full articulation built in. This means you assemble the model relatively fast, but the parts are tiny and densely packed. Some pieces are smaller than a fingernail and require careful nipping from the runner with proper sprue cutters. Sticker application is a real time sink — RG kits include extensive realistic-detail stickers that take longer than you expect.
MG kits build the inner frame from scratch. You spend the first 3 to 5 hours assembling a fully articulated mechanical skeleton — pistons, hydraulic lines, joint clusters — before you put a single piece of armor on. Once the frame is done, you build the armor in panels and snap it over the frame. Parts are larger, easier to handle, and the build feels more rewarding because you can see the engineering underneath the armor when you remove panels.
For a first gunpla build, the RG is more forgiving on tools and patience. For a second or third build, the MG is more satisfying because the inner frame turns the kit into a proper engineering project rather than a single-session assembly.
Detail and visual quality
Both grades are spectacular at this price point. RG packs an absurd amount of panel-line detail into a 13 cm figure — the surface molding is genuinely closer to a 1/100 kit shrunk down than to a basic 1/144. The included realistic-detail stickers add color separation and tech markings that bring it close to a properly painted model.
MG has more room to work with at 18 cm. Panel lines are deeper and easier to ink, color separation comes from molded parts rather than stickers in most cases, and the larger surface area takes weathering and topcoat finishes much better. If you plan to paint or weather your kits, MG is significantly easier to work on.
A built-and-stickered RG can look better on a shelf than a built-but-unfinished MG, because the RG's stickers fill in detail the MG would normally need painted. A built-and-painted MG, however, will out-detail any RG.
Articulation and posability
Both grades pose well. RG's pre-assembled inner frame gives surprisingly wide range of motion for a kit this small — most RGs can hold dynamic action poses, sword stances, or kneeling positions without parts falling off. The trade-off is that the small joints can loosen over time, particularly on heavier RGs like the Strike Freedom with its many backpack components.
MG articulation is broader and more secure. The full-size inner frame supports more weight, the joints are larger and ratcheted, and poses hold longer. MG kits with shoulder-mounted armaments (large weapons, beam cannons, full-burst options) handle the weight without sagging. This is one of the strongest practical reasons to choose MG: posed display kits look better six months later because the joints stay tight.
Price and value
On AliExpress in 2026, RG kits run $25 to $45 and MG kits run $45 to $90, depending on the specific mobile suit and the seller. Both are roughly half the suggested retail price you would pay at a Western hobby store, though shipping from China takes 2 to 4 weeks for standard delivery.
A note on authenticity: AliExpress sells both genuine Bandai kits and "third-party" reboxed copies. Genuine kits include the Bandai logo on the box, the spec card, and a runner-numbering scheme that matches official references. Third-party copies use cheaper plastic that is more brittle and sometimes have warped runners. Filter for sellers with high volume (10,000+ sold) and check buyer review photos before ordering. The price difference between genuine and copy is usually only $5 to $10, so there is no good reason to risk the copy.
For value-per-hour-of-entertainment, MG wins. A $70 MG that takes 15 hours to build delivers about $4.50 per hour. A $35 RG that takes 5 hours delivers about $7 per hour. Both are cheap entertainment by any measure.
Use case: who should buy which
Choose the RG if you:
- Are building your first or second gunpla.
- Have limited shelf space (a 13 cm figure fits on almost any surface).
- Want a complete project finishable in a single weekend.
- Are budget-conscious and want to try the hobby before committing.
Choose the MG if you:
- Have already built one or more HG or RG kits.
- Want a multi-session, deeper build with a full inner frame.
- Plan to paint, weather, or topcoat your kits.
- Have shelf space for an 18 cm figure plus weapon and stand accessories.
The honest answer for most newcomers: start with one RG to learn the workflow (sprue cutters, cleaning nub marks, sticker application), then move to MG once you know you enjoy the process. Skipping straight to MG works if you have built other plastic models before, but the longer build time can overwhelm a brand new builder.
Both grades are excellent. RG is the better starter; MG is the better long-term hobby kit.

Frequently asked questions
Frequently Asked Questions
Not at all. At about 13 cm tall, an RG looks impressively detailed up close and fits on almost any surface. They look especially good in groups of three or four kits posed together.
A pair of sprue (hobby) cutters is the only essential tool. A hobby knife for cleaning nub marks and a small sticker-application tool make the build easier. Glue and paint are not required for either RG or MG.
Yes, especially if you have built plastic models before. New builders sometimes underestimate the part count and build time of MG. Starting with an RG or HG kit first lets you confirm you enjoy the hobby before investing in a 15-hour project.
Most high-volume listings sell genuine Bandai kits. There are some third-party reboxes with cheaper plastic. Check the box for the Bandai logo, filter for sellers with 10,000+ sold units, and read recent buyer reviews with photos to confirm authenticity.
Two RGs give you more variety, a faster sense of progress, and more poses to display. One MG gives you a deeper, more detailed single project. For new builders, two RGs are the better answer; for collectors, one MG.
Final word
Both Real Grade and Master Grade are excellent, and the right answer depends entirely on where you are in the hobby. Start with the RG Strike Freedom if this is your first or second kit — it is faster, smaller, cheaper, and forgiving of the learning curve. Move to the MG once you know you enjoy the workflow and want a longer, more engineering-focused build with a full inner frame. Both grades are widely available on AliExpress in 2026 at roughly half Western retail, and both will give you many hours of enjoyable building per dollar spent.
