The FGC-9 project was started in 2019 by a developer known as “JStark” (later passed away) to demonstrate how modern additive manufacturing could produce functional firearms with minimal regulated parts (only the barrel liner and AR-15 fire control group). The MKII iteration moved further away from commercial parts.
Rev5 represents a late-stage MKII refinement before the community shifted focus to newer platforms (e.g., the FGC-9 Stingray or the entirely different Partisan-9).
From text files included in the archive (typically named CHANGELOG.txt or REV5_NOTES.md), common updates include:
Given the naming and assuming this file comes from a community-driven project or an open-source initiative, FGC-9-MKII-Rev5.zip likely contains:

FGC-9-mkii-rev5.zip refers to a package of digital design files for the FGC-9 MkII Fgc-9-mkii-rev5.zip
(Fuck Gun Control-9), a widely known semi-automatic 9mm pistol-caliber carbine designed to be manufactured using 3D printing and readily available hardware store components. Summary of the FGC-9 MkII Originally released in early 2020 by the group Deterrence Dispensed
, the FGC-9 was designed by the late German-Kurdish designer Jacob Duygu (online pseudonym JStark1809
). Its primary goal is to provide a viable firearm option for individuals in regions with restrictive gun control, as it requires zero regulated firearm parts for its assembly. Key Features of the MkII Design
The MkII (Mark 2) introduced several significant improvements over the original FGC-9: Non-Reciprocating Charging Handle
: A side-mounted handle styled after the MP5 that does not move when the gun fires. Enhanced Reliability
: Revised ejector systems and improved bolt carrier alignment for smoother operation. Global Compatibility : Designed specifically to use metric fasteners The FGC-9 project was started in 2019 by
and standard European steel tubing, making it easier to build outside the United States. Tactical Options
: Includes an M-LOK compatible handguard and a top Picatinny rail for mounting sights and accessories. Expected Contents of the ZIP File A standard release package like "Rev 5" typically includes: FGC 9 Mk 2 Rev. 5by KennyTheDude - Creality Cloud

If you’ve been following the evolution of the FGC-9 (Fuck Gun Control 9mm) platform, you already know that every revision brings new refinements. The latest file set making rounds in certain decentralized repositories is named FGC-9-MKII-REV5.zip.
But what’s actually inside the zip? And why does Rev5 matter from a design or maker perspective? Let’s break down the file structure, reported changes, and the community buzz.
Before extracting any archive, the filename itself provides a wealth of metadata. Let’s break down each segment:
| Component | Meaning | Typical Implication | | :--- | :--- | :--- | | fgc | F*ck Gun Control | The original project codename (emerged circa 2020) | | 9 | Caliber | 9mm Luger/Parabellum | | mkii | Mark II | Second major iteration of the design | | rev5 | Revision 5 | Fifth minor update/sub-version of the MKII | | .zip | Container format | Deflate compression, widely compatible |
The rev5 tag is particularly important. In open-source hardware (OSH) projects, Revision 5 often implies that four previous iterations have been tested, debugged, and improved based on community feedback. It suggests a maturation of the design—addressing issues like layer adhesion weak points, trigger mechanism geometry, or magazine feed ramp angles.
