The MM Firefly 3D Printed Buttstock is a black, 3D printed stock built specifically for the MM Firefly blaster, replacing the stock buttstock with a contoured shape designed to sit against the shoulder more securely during extended play. The printed construction is built for a solid, reliable foundation rather than a flexy add-on, so it holds its shape under normal shooting use.
It's available in two lengths — a 13.5cm Short version for players who want a more compact blaster, and a 17.0cm Long version for a fuller cheek weld and more traditional stock feel. Both fit the same Firefly blaster, so the choice comes down to your build size and shooting stance rather than compatibility. This listing is finished in black to match a stock-color Firefly build.

No Tamiya or BMAX rule names 3D printing, but a closed Tamiya-parts-only list excludes it anyway. What R1, R2 and BMAX v5 actually allow you to modify at home.
