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.

Ideal for steadying your shot against barricades at your next match or as a simple hand stop for short-barreled setups. 

This spacer allows any AR-15 or AR-10 Silent Captured Spring to fit and function in a rifle-length buffer tube.

These O-rings will replace any worn, deformed or lost rings from any JP Silent Captured Spring or Variable Mass Operating System (VMOS™) bolt carrier.

The Auxiliary Spring Rate Kit for the JP Silent Captured Spring (JPSCS) allows precise tuning of your rifle’s operating system to match its specific configuration. These springs are not for the GMR-15  Silent Captured Spring.
