Convert your GK1 air p*stol into a super-light, multifunctional carbine that breaks down without any tools!

Huben Gk1 Tactical Pro Mk2 kit 

This kit is 3D printed with PETG. This material is much stronger and higher melt temperature than PLA. Please be aware there may be some minor imperfections.

This kit turns the Huben GK1 pistol into a compact take down rifle. The kit still allows you to shoot the huben as a pistol by not installing the stock. You get best of both worlds.
