KSC Vz.61 Heavyweight GBB – Walnut Grip Custom
The KSC Vz.61 Heavyweight GBB is a compact submachine gun modeled after the Czechoslovak Vz.61 Skorpion, originally developed in the 1960s for military special forces and police use. Its short barrel and folding stock made it ideal for use in vehicles and confined spaces—a purpose faithfully reflected in this airsoft version.
This model features a heavyweight metal frame and realistic blowback operation. The folding stock and compact size make it especially suitable for CQB scenarios. A CNC-machined walnut grip adds a classic aesthetic and solid handling. Compatible with both Green Gas and HFC134a gas.
