Upgrade set for Snow Wolf Kar98k rifles

Upgrade set for Snow Wolf Kar98k rifles

Upgrade set for Snow Wolf Kar98k rifles  contains essential components for increasing rifle performance without requiring any modifications. All parts are designed as direct replacements for the original components.

The kit includes a lightweight aluminum piston that replaces the factory plastic piston. Six air channels improve seal expansion inside the cylinder, resulting in better air sealing and more consistent performance.

The spring guide is machined from stainless steel and is compatible with both original and upgrade springs. An upgrade spring made from high-quality heat-treated spring steel with anti-corrosion finish is also included.

A steel spring guide support ensures precise alignment within the cylinder and provides improved durability compared to the original design. The piston sear is also manufactured from steel for long service life when using stronger springs.
