GFZ SBL 2.0-EX Upgrade Kit
The GFZ SBL 2.0-EX Upgrade Kit is a conversion kit that increases the potential performance of the base SBL 2.0 designed by GavinFuzzyCustoms. Featuring three color-coded springs, a larger plunger tube volume, and a longer barrel, this add-on is capable of even higher average performance compared to its CQB sibling, all while retaining its characteristic smooth action and toolless takedown system. This Hardware Upgrade Kit includes all the specialty hardware necessary to convert your SBL 2.0 into the EX version, including the longer plunger tube, springs, barrel, and other required components. Additional 3D files are required to adapt to the SBL 2.0-EX version.
