REXFIRE S400 Mod – Hardware Kit

Rexfire’s S400 Mod consists of six parts. These parts are open source and can be downloaded from MakerWorld.

The cheek rest, given by ZWQ, is also open source and can be downloaded via the link on this page.

In addition, the kit includes all required hardware for the appearance mod, but does not include glue or double-sided tape.

The Bazooka Grip is not open source; however, this kit includes one pre-printed grip.

The foregrip and magwell shown in the gallery are not included in this kit and can be purchased separately on this website.

Please Note:

The S400 shown here is my first-batch, paint-chipped ‘battle-worn’ version that nobody wanted, while the ones I sell are from the second batch and don’t have this issue.

The grip used in the Rexfire S400 Appearance Mod is not open-source.

However, this grip is not only highly practical, but also improves both the comfort and height when shouldering your blaster. Its design blends seamlessly with the rest of the build, creating a clean and cohesive look.

With proper authorization obtained, I am offering this kit. The kit includes all the necessary hardware specified in the print files, as well as the grip itself.

• There is no default color configuration — you can customize the colors of the two main parts to match your personal preference.
• The grip features a fuzzy skin texture on both sides, a detail that reflects its origin from a dedicated wargaming enthusiast.
• Please note that screws for buttstock pad may differ slightly from Rexfire’s original specifications, but all included components have been tested and confirmed to work properly.
