Tungsten Weight for JP Silent Captured Spring System - Gen 1
These Tungsten Weights are heavier than the standard steel weights on the Silent Captured Spring and enables the replacement of one or more of the steel weights for those who want greater reciprocating mass. Weights sold individually. Each weight adds approximately 0.6 ounces over the steel weight.
This weight is designed for the JPSCS-15 Gen 1 system. It is not compatible with the Gen 2 since the weights are a different size.
