A new Zinc .50 front part variant supports passthrough barrel configurations, allowing for longer barrels and external BCARs. Use it with either the handguard or rail spacer to fill the space behind it.

This new front part variant has been added to the existing original and cosmetic part variants print file listings. A new cosmetic part variants rail spacer with a sleeker profile is also available.

Zinc .50 205mm barrel hardware kits now include the barrel retention hardware required for these new configurations.

With the release of the new Zinc .50 cosmetic part variants, we are holding a 10% off all hardware kits sale. This discount also stacks with the hardware kit bundle discounts!

These new parts require no hardware changes, and so use the same Zinc .50 Hardware Kits. Find the files for the new cosmetic parts on Printables and Makerworld, along with their corresponding 3MF slicer files with preset per-part settings.
