Overview

Pepperbox Mk II is the latest iteration in the Pepperbox line of 3D-printed foam dart blasters.
Designed by Lao Gong, this version reflects a careful balance between mechanical creativity, ease of fabrication, and overall user experience.


Design Background

The Pepperbox project traces its early roots to the YEHW design by Captain Slug.

Special thanks to Captain Slug for the original YEHW, which served as early inspiration for this project.

Through multiple generations of redesign and experimentation, the Pepperbox platform gradually developed its own distinct character, giving rise to several derivative launchers with different play styles.
Among them, Pepperbox Mk I stood out for its unconventional feeding mechanism and its thoughtful approach to improving hands-on experience.


From Mk I to Mk II

Lao Gong is a designer who places great importance on the completeness and integrity of his work.
For him, a design is not finished at the CAD stage—it also includes how easily it can be printed, how clearly it can be assembled, and the quality of the hardware and packaging that ultimately reach the user.

In response to feedback from the community, Lao Gong revisited the limitations of Pepperbox Mk I that he had previously discussed in his videos.
After several rounds of refinement and validation, these issues were successfully addressed, resulting in Pepperbox Mk II.


Product Experience

From the product images and videos, it is easy to see that Pepperbox Mk II is designed with accessibility in mind.
The print files are straightforward, the printing difficulty is low, and the assembly process is intentionally kept simple and intuitive.

At the same time, the blaster retains a playful and engaging operating style, making it enjoyable both to build and to use.

Consistent with Lao Gong’s long-standing approach, any upgrade that requires new hardware will be provided free of charge.
This website follows the same policy in accordance with the designer’s wishes.


Performance Notice

Pepperbox Mk II operates at approximately 120 FPS.

⚠️ This product is not intended for high-FPS competitive war games.
Players who prioritize maximum muzzle velocity should consider this carefully before purchasing.


Additional Notes

Print time and filament usage may vary depending on printer, slicer, and print settings.
Assembly instructions and related files are provided by the designer.
