JP konverzní sada na short stroke pro pušky 9 mm

JP Enterprises JPSCS2-9SS-4-5K is a conversion kit for the Silent Captured Spring (SCS Gen 2) system designed for the AR-15 platform in 9 mm. It is used to convert a standard 4-weight 9mm SCS to a short-stroke configuration with a different weight arrangement for tuning the firearm's cycling.

The kit allows optimization of the bolt cycle in PCC (pistol caliber carbine) configurations, particularly to achieve reliable function with various types of ammunition and firearm setups. The conversion changes the internal weight composition (steel/tungsten) and adjusts buffer movement dynamics, enabling smoother or more robust cycling depending on the configuration.

The JP SCS system eliminates the conventional buffer tube spring and replaces it with a self-contained unit with a guided spring, reducing vibration, noise, and improving cycle consistency.
The conversion kit is intended for Gen 2 9mm SCS units compatible with the JP system (bronze guide rod variant).
