Bandai Spirits has announced the release of the Option Parts Set Gunpla 17 (Binder Gun), the seventeenth installment in its popular line of customization accessories. Scheduled for a regular retail release in July 2025, this versatile set delivers a modular and multifunctional system designed to ignite modeler creativity and enhance any 1/144 scale Gunpla kit.
Priced at approximately 660 JPY (price may vary by retailer and region), this set is a must-have for builders looking to add a unique touch to their High Grade (HG) and Entry Grade (EG) models.
Key Features and Versatility
A key feature of the "Binder Gun" is its system of interchangeable parts that invite experimentation. In its base configuration, the components attach to a Gunpla's backpack to function as powerful "binders," dramatically improving the mobile suit's silhouette and visual presence.

The set includes binder parts, a core gun piece, and a versatile joint set for maximum creativity (Image via Bandai Hobby).
However, the customization does not end there. The components can be reconfigured into individual weapons, including a sword mode, a rifle mode, and defensive shields. By combining all the main parts, modelers can assemble the massive and powerful "Binder Gun" configuration. Adherence to the standard 3mm peg system ensures broad compatibility across the HG and EG lines, making this set a versatile tool for advanced customization and "kitbashing."
