FGC-EVO Mod

FGC-EVO Mod Features

The FGC-EVO Mod stands out with its focus on enhancing the performance and aesthetics of the FGC-9 MkII. This modification pack introduces compatibility with CZ Scorpion EVO double-stack 9mm magazines, known for their curved design that ensures reliable feeding and alignment.

Key highlights include:

• Improved Feeding: The curved magazine design minimizes feeding issues, offering a smoother operation compared to traditional Glock magazines.
• Ease of Loading: Double-feed functionality makes reloading faster and more efficient.
• Unique Aesthetics: These magazines add a distinctive, cool look to your firearm build.
• Simplified Modification: Requires only a new upper and lower receiver, feed ramp, and bolt for integration.

For those with an existing FGC-9 MkII, adapting certain components like the bolt and upper receiver may be possible without a full rebuild. Additionally, the mod’s bolt maintains backwards compatibility with the original FGC-9 MkII, ensuring versatility for users.

Difficulty & Build Time

• Skill Level: Intermediate
• Estimated Build Time: 1-2 days
• Required Experience: Familiarity with 3D printing firearms and basic assembly of the FGC-9 MkII; prior experience with firearm modifications is recommended.

Hardware and Tools Required

Required Hardware

• New upper receiver for FGC-9 MkII (specific to FGC-EVO Mod)
• New lower receiver for FGC-9 MkII (specific to FGC-EVO Mod)
• New feed ramp compatible with CZ Scorpion EVO magazines
• New bolt (backwards compatible with FGC-9 MkII)
• CZ Scorpion EVO double-stack 9mm magazines (can be 3D printed)

Recommended Tools

• 3D printer with compatible settings for firearm components
• Basic hand tools for assembly (screwdrivers, wrenches)
• Calipers for precise measurements during modification
• Sandpaper or finishing tools for post-print smoothing
• Safety gear (gloves, eye protection) for handling printed parts

FGC-EVO Mod Parts

The FGC-EVO Mod includes digital files for printing the necessary components to adapt your FGC-9 MkII. These likely include STL files for the new upper and lower receivers, feed ramp, and bolt, though specific file contents should be verified upon download. For optimal results, print with high-strength materials like PETG or ABS to ensure durability under stress.

It’s recommended to use a layer height of 0.2mm or lower for detailed parts and a high infill percentage (50-80%) for structural integrity. Pay attention to cooling settings to avoid warping, especially on larger components like the receivers. Always inspect printed parts for defects before assembly to ensure safety and functionality.

Printer Compatibility & Settings

The FGC-EVO Mod is compatible with most FDM 3D printers capable of handling detailed firearm components, such as Ender 3, Prusa i3, or similar models with a build volume sufficient for larger parts like receivers. Recommended materials include PETG or ABS for their strength and heat resistance, though advanced users may opt for nylon for added durability.

Set your printer to a nozzle temperature of 230-250°C for PETG or 240-260°C for ABS, with a bed temperature of 80-100°C to ensure proper adhesion. Use supports for overhangs on complex geometries like the feed ramp, and consider a brim or raft for larger parts to prevent lifting. Ensure proper ventilation when printing with ABS due to fumes, and always prioritize safety during the printing process.

Conclusion

The FGC-EVO Mod is a must-have for FGC-9 MkII owners looking to elevate their firearm’s performance with the reliable and stylish CZ Scorpion EVO magazines. With its straightforward modification process and backwards-compatible bolt, this pack offers both practicality and innovation for 3D printing enthusiasts.
