JP Gen 2 Buffer Mass Tungsten Weight for JP SCS Units

Tungsten Weight for Silent Captured Spring/VMOS™ Carrier

Designed to replace one or more of the existing weights of the JP Silent Captured Spring or VMOS™ Bolt Carrier, these tungsten weights are the standard components used for reciprocating mass in the operating system.

SCS Generation Selection
To ensure compatibility with your unit, verify that you have a GEN 2 Silent Captured Spring unit. The mass sliders of the first generation SCS are black while the GEN 2 sliders are bronze.
VMOS™ carriers use the same masses as the GEN 2 Silent Captured Springs.
