VP22 Bolt action pistol

VP22 Bolt Action Pistol Features

The VP22, also known as Ветеринарний Пістолет-22, stands out with its bolt-action mechanism and optional suppression, ideal for discreet, low-noise operation. Its design allows for a compact form factor, as it can be fired without the grip/magazine attached, enhancing portability.

Key highlights include:

• Grip Safety: Ensures secure handling during operation.
• Integral Magazine: Seamlessly built into the grip for streamlined design.
• Ammunition Versatility: Safely fires High Velocity .22LR, with optimal performance using 22LR Subsonic or 22LR CCI Quiet for reduced noise, and even quieter with 22 Colibri.

This pistol requires only a few metal components, such as a barrel liner, breech face, bearings, springs, and pins, keeping the build accessible. With less than 0.5kg of filament needed and minimal support during printing, it’s a practical choice for DIY firearm projects.

Difficulty & Build Time

• Skill Level: Intermediate
• Estimated Build Time: 1-2 days
• Required Experience: Basic knowledge of 3D printing, metalworking (grinding and drilling), and firearm safety; familiarity with epoxy reinforcement recommended.

Hardware and Tools Required

Required Hardware

• Barrel liner (.305, .315 specifications)
• Breech face (1/8" steel insert for bolt)
• 2 bearings
• Springs and pins
• Fasteners
• M3 rods (for reinforcing the rear of the upper)
• Epoxy (for securing components and reinforcement)

Recommended Tools

• 3D printer (compatible with recommended materials)
• Grinder (for shaping metal breech insert)
• Cobalt drill bits (2.5mm for striker hole)
• Drill (for creating precise holes)
• Sandpaper or deburring tools (for removing burrs)
• Q-tip stems (to prevent epoxy from clogging holes)

VP22 Bolt Action Pistol Parts

This downloadable file includes STL files for the VP22 Bolt Action Pistol, covering all printable components like the upper, grip/magazine, and bolt assembly. For optimal results, print with durable materials like PETG or ABS to withstand the mechanical stress of operation. Only one part requires support during printing, simplifying the process.

Special considerations include reinforcing the rear of the upper with epoxy and M3 rods, especially if using ammunition stronger than subsonic or CCI Quiet. The breech metal insert must be cut from 1/8" steel using the provided template (included in STEP files), then ground to fit and drilled for the striker. Detailed assembly guidance is available in the PDF guide linked at build instructions.

Printer Compatibility & Settings

The VP22 design is compatible with most FDM 3D printers capable of handling durable materials like PETG or ABS, which are recommended for their strength and heat resistance. PLA may not be suitable due to the mechanical demands of a firearm. Use standard print settings with a layer height of 0.2-0.3mm for a balance of detail and strength, and ensure minimal support structures as only one part requires them.

Ensure your printer bed is leveled and calibrated for precision, as tight tolerances are critical for functional assembly. For best results, print at a moderate speed to avoid warping, and consider a brim or raft for better bed adhesion on smaller components.

Conclusion

The VP22 Bolt Action Pistol offers a remarkable blend of historical inspiration and modern 3D printing innovation, making it a standout project for firearms and DIY enthusiasts. With its compact design, optional suppression, and minimal material requirements, it’s an accessible yet rewarding build for intermediate makers.
