Gen 3 Stock System Parts

The Gen 3 Stock System includes a comprehensive set of STL files for printing the fixed stock, butt pads, and adapters. These files allow for full customization, with options for three butt pad designs and five stock lengths to suit individual preferences. Additionally, four adapter designs ensure compatibility with various lowers, including Hoffman Tactical models and mil-spec aluminum lowers.

For optimal results, print the main stock components using a durable material like PETG or ABS to withstand the rigors of use. Butt pads can be printed in TPU for added comfort and shock absorption. Ensure proper layer adhesion by using a heated bed and consider a brim or raft for larger parts to prevent warping during printing.

Printer Compatibility & Settings

The Gen 3 Stock System is compatible with most FDM 3D printers capable of handling standard filament sizes (1.75mm or 2.85mm). Recommended materials include PETG or ABS for the stock and adapters due to their strength and impact resistance, while TPU is ideal for butt pads to provide flexibility and comfort.

Print settings should include a layer height of 0.2-0.3mm for a balance of detail and speed, with an infill density of 20-30% for lightweight yet sturdy components. A nozzle temperature of 230-250°C (for PETG/ABS) and a bed temperature of 80-100°C are suggested to ensure proper adhesion. Always verify your printer’s build volume can accommodate the larger stock components, and refer to the provided PDF guide for detailed assembly instructions.

Conclusion

The Gen 3 Stock System is an exceptional choice for AR-15 owners seeking a customizable, lightweight, and durable stock solution through 3D printing.
