JP Enterprises Gen 2 AR-15 Silent Captured Spring

The JP EnterprisesA(R) Gen 2 AR-15 Silent Captured Spring is designed to be quieter and get rid of the springy sound that's exaggerated when shooting suppressed. Includes spacer to allow for installation in both 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.
