JP Enterprises AR-15 Silent Captured Spring Gen 2 H2

The JP Enterprises Gen 2 Silent Captured Spring takes the place of the loose buffer and spring in an AR-15 with one self-contained, patented assembly. This is the H2 version, built with the buffer mass of an H2 buffer. A spacer comes in the package, so the same unit installs in a carbine length or a rifle length buffer tube.

JP recommends the H2 version for short barreled rifles, suppressed rifles, select fire rifles, piston operated rifles and any rifle that calls for an H2 buffer. If your rifle runs hot with a suppressor on it, this is the JP option to look at.
