Unlike many earlier 3D-printed firearm projects, which often required unregulated pre-existing firearm parts (such as a manufactured metal receiver or an AR-15 lower parts kit), the FGC-9 was specifically engineered to be built using entirely unregulated commodities. This concept is often referred to as a "zero percent" build. The design relies heavily on the use of components manufactured via FDM (Fused Deposition Modeling) 3D printing and commercially available metal stock, such as pipes and flat steel bars.

• .stl files : These are the printable components. For rev5, expect between 25–35 individual STLs (upper receiver, lower receiver, grip, handguard, magazine body, follower, buttstock components).
• .step or .stp : Parametric solid models. A rev5 update often includes STEP files for CNC modification or remixing.
• bill_of_materials.csv : Revision 5 often updates spring constants (e.g., changing from 0.8mm to 1.0mm music wire) or screw lengths.
• assembly_manual_rev5.pdf : Detailed diagrams with torque values and post-processing steps (e.g., drilling pin holes, tapping threads).

Integrated M-Lok Slots

: The extended barrel retainer now includes M-Lok slots, finally giving makers a standardized way to mount lights or grips. Would you like a breakdown of the file structure (e
