GEN 2 AR-15 Silent Captured Spring Builder with Alternative Spring Pack
Includes SCS unit, five alternative weight springs and spacer to allow for installation in both carbine- and rifle-length buffer tubes.
Weight: 5.3 oz. (final SCS unit)
The JPSCS2-15 will not function with older Primary Weapon Systems (PWS) bolt carriers. The design of the carrier will prevent the rifle from cycling.
See our FAQ section if you have more compatibility questions.
SCS Buffer Retainer Pin
Because the insertion and removal of the Silent Captured Spring is very difficult with a standard buffer retainer pin, we recommend removing it when installing your SCS. This leaves the SCS "free-floating" in the buffer tube. While this isn't a problem when the receivers are closed, some shooters find it objectionable. In this case, we have a custom Silent Captured Spring Buffer Retainer Pin and Spring available to retain the SCS without the snagging caused by the Mil-spec design.
