JP Enterprises AR-15 Silent Captured Spring Gen 2

This is the standard version of the JP Enterprises Gen 2 Silent Captured Spring for AR-15 type rifles. The patented assembly holds the operating spring and buffer weights together as one unit, so it drops into the receiver extension in place of a conventional buffer and spring.

JP packs a spacer with it, which lets the same assembly run in either a carbine length or a rifle length buffer tube. Pick the standard version for a typical gas gun; JP sells H2 versions for suppressed, short barreled and other rifles that want more buffer mass.
