Bandai 1/144 Option Parts Set Gunpla 13 (Gunpla Battle Arm Arms)

A weapons-and-armour pack to kit out any 1/144 Gunpla. Option Parts Set Gunpla 13 is the Gunpla Battle Arm Arms set from the Gundam Build line. It loads a stack of weapons, armour and boosters that clip onto most 1/144 kits, so you can re-arm or rebuild a Gunpla into your own custom.

What's in the set. A sword, an axe, two boosters, two missile launchers, two stabilizers, a shield, a multi-mount, waist armour, two intakes, a set of joint parts, and stickers. Plenty to spread across a build or two.

How it fits. The parts use the standard 3mm ports, so they work with most 1/144 Gunpla and other 3mm kits like 30MM. Mix and match for a melee, ranged or heavy loadout.

Build notes. Snap-fit, no glue needed, moulded in colour. Stickers included.

Fast Australian shipping. Order before 2pm on a weekday and it ships the same day from Brisbane.

What to watch for. This is a parts pack, not a kit with a mobile suit in the box. You need a Gunpla to attach it to.

Assembly Guide

SKILL LEVEL REQUIRED
Skill Level.2 Basic modeling skills are required. Parental supervision may be required for younger children. These kits are generally suitable for beginner builders. A basic set of modeling tools are required including nippers, hobby knife, sanding sticks/paper, file, and tweezers. No glue is needed for the general assembly. Parts will need to be removed by using a pair of nippers and cutting the part away from the runner. Parts may require clean-up where they were removed from the runner.
No Cement Required

Gunpla (plastic model kits) are a snap together assembly and do not need plastic cement to complete. We always recommend having some plastic cement handy as a part of your modeler's tool kit. If you prefer to fix your model in a particular pose then plastic cement will work. Plastic cement is also perfect to use if a joint is loose. Apply plastic cement in a single thin layer and allow it to dry completely before test fitting. Re-apply more cement if necessary.

No Painting Required

Gunpla (plastic model kits) are designed to be built and displayed without the need for painting. Kits are molded in different colours replicating the colours of the actual mecha from the Mecha series. A technique called colour separation, where multiple parts of the model are molded in different colours on the same sprue is also used. Mecha kits often include stickers or water-slide decals that can be applied to the model to enhance its appearance. Some Gunpla kits come with pre-painted parts or parts with pre-applied details, such as metallic or translucent finishes.

Many modelers still choose to paint their kits to customize and add further detail. Painting allows for more creativity and personalization, enabling modelers to achieve unique effects, weathering, and colour schemes that may not be available out of the box. However, the kits are designed to be enjoyable and visually appealing even without painting, making them accessible to a wide range of hobbyists.

Frequently Asked Questions

What makes these Gunpla kits the hottest sellers?

These kits are fan favourites for their detailed design, affordability, and build size, offering a balanced and enjoyable building experience.

Are these hottest seller kits suitable for beginners?

Absolutely! Especially the HG kits, which are known for their fewer parts and simplicity, making them a great starting point for new builders.

What is the level of detail in the MG and RG hottest sellers?

MG kits boast a detailed inner frame and additional parts, while RG combines MG’s complexity with HG’s size for an intricate, compact build.

Can I get replacement parts if I lose some during the build?

Yes, if you buy a kit from Gundam Express Australia we will source replacement parts for you. This is not a quick process as parts need to come from Bandai in Japan.

How much space will I need to display these Gunpla?

HG and RG Gundam kits are compact, while MG Gundam are larger but still manageable. You won’t need too much space to showcase these masterpieces beautifully.

Amazing Build, my Grandson loved it!

I purchased this kit and one other for my grandsons birthday. He loved building it and found it easy to follow. My order arrived in super fast time and was beautifully packed. It even had some wonderful freebies in the box which was really great. Excellent product and service in every way!

Great selection of kit, excellent value for money

Awesome kit, great extras. Only criticism is that the kit comes with a base so you don't need the second one. The kit also doesn't have the ability to take the blue LED bonus so if you don't have another use for it it is wasted. Luckily, I'm a Gundam tragic so will always have uses for extra bases and lighting kits.

Excellent service and fast delivery

I purchased on 6 Jan and my order arrived on 13 Jan. It was very well packed, with both boxes in excellent condition. Cam even provided a small free gift in the box! Overall purchasing experience was smooth and hassle-free. I haven’t had the chance to build the kit yet, but based on the service and care taken with shipping, I would happily purchase from this store if there are other Space Battleship Yamato models available.

Very rare with fair price

If you were one of the lucky ones that were able to travel to Sydney Gundam Base pop-up in 2025 and queued extremely early (like the first 40 or so) on the first day, probably you were able to grab one of these. Otherwise, the only alternative I would know of is traveling to Japan and being uber lucky of having it still being sold at Gundam bases. Otherwise, it's a second-hand market, and prices will go up. That said, the price was fair, I think it would be similar price as using a dropship service from Japan, with the exception that it's much faster and way more guaranteed you will get proper merchandise. So, Mecha Express, Cam, thank you so much for your store!
