DB Firearms Presents: DB Alloy Features

The DB Alloy stands out as a modular hybrid lower receiver, combining the flexibility of 3D printing with the durability of steel components. Its design is meticulously crafted to ensure compatibility with Mac 11/9 and Mac 5.7 upper receivers, making it a versatile choice for firearm enthusiasts.

Key highlights include:

• Magazine Versatility: Supports Glock mags, Sten mags, 3D-printed Sten mags, and FN Five-seveN mags for maximum customization.
• Popular Add-Ons: Enhance your build with community favorites like the Charging Handle Cover by dogenado, Handguard by Krrawn, and the DB Ridgeback AR Grip.
• Hardware and Accessories: Easily source hardware kits from DB Design Works and side plates from Riptide Rails for a complete assembly.

This design prioritizes adaptability, allowing builders to tailor their firearm to specific needs. With detailed instructions in the included readme, even complex modifications like fitting a Sten latch are made accessible.

Difficulty & Build Time

• Skill Level: Intermediate
• Estimated Build Time: 2-3 days (including printing and assembly)
• Required Experience: Basic knowledge of 3D printing, firearm assembly, and working with adhesives like JB Weld for magazine modifications.

Hardware and Tools Required

Required Hardware

• Glock 33-round magazine spring or equivalent (for printed mags)
• Hardware kits (available at DB Design Works)
• Side plates (available at Riptide Rails)
• JB Weld Clear Weld (for Sten latch installation on metal mags)

Recommended Tools

• 3D printer for printing components
• File or sandpaper (for fitting Sten latch and magazine adjustments)
• C-clamp (for securing Sten latch during drying)
• Cleaning supplies (to remove residue and oil from magazines)

DB Firearms Presents: DB Alloy Parts

The DB Alloy file package includes STL files for various components such as magazine bodies, followers, baseplates, locks, and the Sten latch for modifications. These parts are pre-oriented for optimal printing, ensuring ease of use straight from the download. For best results, use PLA+ or stronger materials to ensure durability, especially for functional components like magazine parts.

Special considerations include testing the fit of printed magazines in the assembled firearm before final adhesion. For metal Sten mags, follow the detailed readme instructions for filing and gluing the Sten latch, ensuring a secure and functional fit. A build instructions PDF is also available for comprehensive guidance on assembly.

Printer Compatibility & Settings

The DB Alloy components are compatible with most FDM 3D printers capable of handling detailed prints. Recommended materials include PLA+ or stronger filaments to withstand the mechanical stress of firearm components. Print settings should prioritize high infill (at least 50-75%) and layer heights of 0.2mm or finer for precision in functional parts like magazine lips and latches.

Ensure your printer bed is leveled and adhesion is strong to prevent warping during long prints. For optimal results, avoid brittle materials like standard PLA and test small components before committing to full builds. No special printer requirements are noted beyond standard calibration and maintenance.
