SG22 Bullet Bill Upper Parts

The SG22 Bullet Bill Upper file includes STL files for the main upper receiver component, designed for 3D printing with high precision. These files are optimized for a smooth printing process, though attention to detail during post-processing is recommended to achieve a polished look. For best results, print with a high infill percentage (50-75%) to ensure structural integrity under the stresses of firearm use.

We suggest using durable materials like PETG or ABS to balance strength and flexibility, as these materials can withstand the rigors of assembly and use. Ensure proper bed adhesion and consider using supports for overhangs to maintain the intricate details of the Bullet Bill design. After printing, light sanding and finishing can elevate the final appearance of your upper.

Printer Compatibility & Settings

The SG22 Bullet Bill Upper is compatible with most FDM 3D printers that have a build volume sufficient for firearm components (minimum 200mm x 200mm x 200mm recommended). For optimal results, use materials like PETG or ABS, as they offer the durability needed for functional firearm parts. PLA is not recommended due to its lower strength and heat resistance.

Set your printer to a layer height of 0.2mm for a balance of detail and speed, with an infill of 50-75% to ensure robustness. A nozzle temperature of 230-250°C (depending on material) and a bed temperature of 80-100°C will help achieve consistent prints. Always double-check your printer’s calibration to avoid warping or dimensional inaccuracies, especially for parts requiring tight tolerances.

Conclusion

The SG22 Bullet Bill Upper is an exciting addition to any 3D printing or firearms enthusiast’s collection, offering a blend of unique design and practical application for 22LR builds. Its eye-catching Bullet Bill aesthetic, combined with compatibility for SG22 systems, makes it a rewarding project for intermediate builders.
