LR-308 Super Lower V2.6 Parts

This downloadable file includes the STL files necessary to print the LR-308 Super Lower V2.6, a meticulously designed lower receiver by Hoffman Tactical. For optimal results, refer to the included README for generic print settings and guidance. Due to the length of the lower, printing diagonally on the bed may be required to fit within standard printer dimensions.

It’s recommended to use durable materials like PETG or ABS to ensure the part withstands the stresses of firearm use. Post-processing may be needed to smooth surfaces and ensure proper fitment with your chosen upper. Detailed build instructions are also available as a PDF guide at this link for step-by-step assembly support.

Printer Compatibility & Settings

The LR-308 Super Lower V2.6 is compatible with most consumer-grade FDM 3D printers, provided the bed size accommodates the part’s dimensions (diagonal printing may be necessary). For best results, use materials like PETG or ABS to balance strength and flexibility, as these are ideal for functional firearm components. PLA is not recommended due to its lower durability under stress.

Print settings should prioritize high infill (80-100%) and a layer height of 0.2mm or lower for precision. Ensure proper bed adhesion and consider using a brim or raft to prevent warping during printing. Always refer to the included README for Hoffman Tactical’s specific recommendations on settings tailored to this design.

Conclusion

The LR-308 Super Lower V2.6 is a game-changer for 3D printing and firearms enthusiasts, offering a robust, compatible, and highly customizable lower receiver for LR-308 and SR-25 builds. With its array of improvements and detailed build support, this design empowers builders to create reliable rifles for 308 or 6.5 Creedmoor configurations.
