JP Enterprises Gen 2 AR-15 Silent Captured Spring Builder Kit

The JP EnterprisesA(R) Gen 2 AR-15 Silent Captured Spring Builder Kit includes a Silent Capture Spring (SCS) unit as well as 5 alternative weight springs and spacers. This kit can be used with carbine- and rifle-length buffer tubes. Because the insertion and removal of the Silent Captured Spring is very difficult with a standard buffer retainer pin, JP Enterprises recommends removing it when installing your SCS. This leaves the SCS "free-floating" in the buffer tube.
