Bandai 1/144 Option Parts Set Gunpla 17 (Binder Gun)

Binder Gun, Option Parts Set Gunpla 17

The 17th release in Bandai's Option Parts Set line is the Binder Gun, a joint-part-driven weapon accessory built to bolt onto the back of a compatible 1/144 HG kit. Mounted as a binder, it strengthens the pose on your kit's back unit. Attach a grip to the binder and it switches into sword mode or rifle mode, so one set gives you three different loadout options.

It's a snap-fit accessory. No cement and no paint are needed to get a clean result straight off the runner.

What's in the box

  • Binder parts: large and small, two of each
  • Gun parts: one set
  • Joint parts: one set

Compatible kits

The Binder Gun is built for the 1/144 HG line generally, rather than one specific kit. Bandai's own listing recommends trying it across the HG series to build your own loadout. Any HG kit with a standard 1/144 backpack mount is a reasonable fit. No display base is included with the set.

Fast Australian shipping

Dispatched same day from Brisbane if ordered before 2pm AEST on weekdays. Free shipping Australia-wide on orders over $199. Packed securely in a sturdy outer box with water-soluble cornstarch void fill that dissolves cleanly in the sink.

Assembly Guide

SKILL LEVEL REQUIRED
Skill Level.1. Most adults & children can assemble Skill Level 1 kits with little to no difficulty. Very basic hobby tools are recommended including a pair of nippers, a hobby knife, but are not essential. No Glue is needed for these kits. Kits are all snap together build and most parts can be removed by twisting and pushing without the need to snip with nippers.
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

Is the Binder Gun compatible with all 1/144 scale Gunpla kits?

The Binder Gun is designed for 1/144 scale kits, including HG and RG models. However, minor modifications may be needed for a perfect fit on some kits.

This set requires assembly and detailing, just like standard Gunpla kits. It’s perfect for builders who love customization and painting.

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!

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!
