The Monarch and The Apple Pie

The Monarch and The Apple Pie Features

The Apple Pie pump-action AR-15 stands out with its versatile caliber compatibility, making it a must-have for firearm enthusiasts. This design has been rigorously tested in popular calibers like 5.56, 7.62x39, 300BLK, and even .458 SOCOM, ensuring reliable performance with a locked bolt system.

Key highlights include:

• Manual Pump Action: Offers a unique, hands-on shooting experience distinct from traditional semi-auto AR-15s.
• 22lr Conversion Compatibility: While not suited for pistol calibers, it supports 22lr conversion bolts, functioning in semi-auto mode with the pump as a forward charging handle.
• Community Engagement: Share your builds on social media by tagging 3D Arms and Middleton Made for a chance to be featured.

This design prioritizes simplicity, making it an accessible project for those with spare AR-15 components. It’s a perfect blend of innovation and practicality for DIY firearm projects.

Difficulty & Build Time

• Skill Level: Intermediate
• Estimated Build Time: 1-2 days
• Required Experience: Basic knowledge of AR-15 components and 3D printing; familiarity with firearm assembly recommended.

Hardware and Tools Required

Required Hardware

• Standard AR-15 components (barrel, bolt, and receiver parts compatible with locked bolt operation)
• Compatible calibers (5.56, 7.62x39, 300BLK, or .458 SOCOM)
• Optional 22lr conversion bolt for semi-auto functionality

Recommended Tools

• 3D printer for printing the Apple Pie components
• Basic hand tools for AR-15 assembly (wrenches, screwdrivers)
• Finishing tools for post-processing printed parts (sandpaper, files)
• Safety equipment (gloves, eye protection) during assembly and testing

The Monarch and The Apple Pie Parts

This downloadable file includes the necessary STL files for printing the Apple Pie pump-action AR-15 components. These files are designed to work seamlessly with standard AR-15 parts, allowing for a custom build tailored to your preferred caliber. For optimal results, print with high-strength materials and ensure proper layer adhesion to withstand operational stress.

It’s recommended to use a layer height of 0.2mm or finer for detailed components and to print with at least 50% infill for durability. Pay attention to critical stress points during printing, and consider reinforcing key areas with additional supports if needed. Detailed build instructions are available as a PDF guide at this link.

Printer Compatibility & Settings

The Apple Pie design is compatible with most FDM 3D printers capable of handling detailed firearm components. Recommended materials include PETG or ABS for their strength and heat resistance, though high-quality PLA+ can work for less demanding builds. Avoid standard PLA due to its brittleness under stress.

Set your printer to a nozzle temperature of 230-250°C for PETG or ABS, with a bed temperature of 80-100°C to prevent warping. Use a brim or raft for better bed adhesion, especially for larger parts. Ensure proper cooling and ventilation when printing with ABS to manage fumes safely.

Conclusion

The Monarch and The Apple Pie offers a rewarding challenge for 3D printing and firearms enthusiasts, combining the thrill of a custom build with the innovation of a pump-action AR-15.
