PCP airgun parts and accessories for 3D printing

This collection brings together 3D-printable parts for pre-charged pneumatic airguns, from magazines and moderators to barrel bands and fill adapters. You will find components for various calibers and mounting standards. Check each STL page for dimensions, thread specs and assembly notes before sending files to your 3D printer.

About the category

«PCP airgun parts and accessories for 3D printing»

The collection includes several functional groups. Rotating magazines and single-shot trays feed pellets in different calibers. External moderators, silencers and internal baffles attach to barrels with various thread standards. Stabilizers, barrel bands and reservoir adapters mount to different air tube diameters, while regulators and valves control air flow.

When choosing a model, verify the thread pitch, caliber and mounting diameter against your airgun. Look at how many parts need assembly and whether the author recommends support structures. Review the material and settings listed on the model page, and compare any photos of real prints to the listed dimensions before loading the STL.

To refine your search, try synonyms such as pre-charged pneumatic, air rifle, suppressor, moderator, hopper or fill probe. You can also search by thread size, caliber or bottle volume. Related topics include pellet holders, scope mounts and general airgun maintenance tools.

FAQ

Frequently asked questions

What thread standard do PCP moderators usually use?
Common examples include 1/2 inch UNF, but thread types vary by manufacturer. Check the model description for exact pitch and diameter, then verify it matches your barrel.
Can I print a PCP magazine in standard PLA?
Some authors list PETG or nylon for spring tracks and feed lips due to wear. Review the recommended material on the model page before choosing filament.
What is the difference between a moderator and a baffle?
A moderator is the complete external housing that threads onto the barrel, while baffles are the internal discs that disrupt air flow. Some models offer only the baffle stack for use inside an existing tube.
How do I choose the right reservoir adapter for my airgun?
Compare the adapter's internal diameter and mount spacing to your bottle or tube dimensions. Look for photos of real prints and any notes the author provides about assembly.
