SpaceGat 22 (SG22) .22LR AR15 Pistol

SpaceGat 22 (SG22) .22LR AR15 Pistol Features

The SpaceGat 22 stands out with its sci-fi-inspired design, offering a visually striking alternative to traditional AR15 pistols. Its printable receiver set allows for full customization, letting you bring a futuristic firearm to life right from your 3D printer.

Key highlights include:

• Lightweight Construction: Designed to be both portable and durable for .22LR use.
• CMMG Compatibility: Engineered specifically for a CMMG Bolt Carrier Group and 4.5" barrel, ensuring seamless integration.
• AR Pattern Design: Utilizes a standard AR Fire Control Group (FCG) for familiarity and ease of assembly.

This model prioritizes safety and precision, making it a reliable choice for hobbyists who value both form and function. Note that it is strictly for .22LR use with CMMG-style BCGs to prevent catastrophic failure.

Difficulty & Build Time

• Skill Level: Intermediate
• Estimated Build Time: 2-3 days (including printing and assembly)
• Required Experience: Familiarity with 3D printing, basic firearm assembly, and AR15 components is recommended.

Hardware and Tools Required

Required Hardware

• CMMG Bolt Carrier Group with 4.5" Barrel (22D5B6E)
• AR Lower Parts Kit (LPK) - excluding Bolt Catch, roll pin, spring, buffer detent, and spring

Recommended Tools

• 3D Printer (FDM compatible)
• Allen wrenches and screwdrivers for AR assembly
• Sandpaper or finishing tools for post-processing printed parts
• Drill (if minor fitting adjustments are needed)

SpaceGat 22 (SG22) .22LR AR15 Pistol Parts

This downloadable file includes STL files for the upper and lower receivers of the SpaceGat 22, designed to be printed and assembled into a fully functional .22LR AR15 pistol. For optimal results, use high-strength materials like PETG or ABS to ensure durability under firing stress. Print with a high infill percentage (50-75%) and at least 5-6 wall layers to maintain structural integrity.

Special considerations include ensuring precise calibration of your printer to avoid dimensional inaccuracies. Post-processing may be required to smooth surfaces and ensure proper fitment with hardware components. Detailed build instructions are available as a PDF guide at this link to assist with assembly.

Printer Compatibility & Settings

The SpaceGat 22 files are compatible with most FDM 3D printers capable of handling detailed and structural prints. Recommended materials include PETG or ABS for their strength and heat resistance, crucial for firearm components. PLA is not advised due to its lower durability under stress.

Suggested print settings include a layer height of 0.2mm for a balance of detail and speed, a nozzle temperature of 230-250°C (depending on material), and a bed temperature of 80-100°C. Ensure proper bed adhesion and consider using a brim or raft for larger parts to prevent warping. A well-calibrated printer with a build volume of at least 200x200x200mm is ideal for accommodating the receiver components.

Conclusion

The SpaceGat 22 (SG22) .22LR AR15 Pistol is a groundbreaking project that combines the thrill of 3D printing with the passion for firearms, delivering a one-of-a-kind sci-fi aesthetic. Its lightweight design, compatibility with CMMG components, and detailed build guide make it an accessible yet exciting endeavor for intermediate builders.
