JP AR10 Silent Captured Spring Builder Kit H2 Buffer

JPSCS2-10K-H2 | AR10 Silent Captured Spring, H2 Buffer version

The “spoon over a cheese grater” sound emitted by modern sporting rifles when charged or fired has always been one of the AR platform’s ugly blemishes and one that the JP AR10 Silent Captured Spring Builder Kit Heavy eliminates.  After years of specially selecting buffer tube manufacturers based on the quality of their tubes’ interior finish, JP opted to design and produce the JP AR10 Silent Captured Spring with a perfect centerless-ground and precision-polished outside diameter.  These JPSCS are an inexpensive way to see exactly why JP has a reputation for the quietest, smoothest rifles available.

Our pursuit of perfection didn’t stop with springs though and led ultimately to the creation of the patented Silent Captured Spring in 2012. Maintaining all the benefits of our polished buffer springs and proprietary LMOS™ buffer, this combination buffer-spring assembly eliminates the friction of standard buffer components resulting in outstanding smoothness and sound abatement.  The spring is removable from the assembly for custom tuning.  Both the AR-15 and AR-10 versions of the JPSCS are functional in rifle and carbine length operating systems.  The AR15 version fits and functions in any gas-operated AR15 variant, regardless of caliber and the AR10 version should fit and function in any large-frame AR10-type platform. The JPSCS is not compatible with any 9mm AR variant or any blowback system using a solid (weighted) carrier.

Gen 2 Improvements

Generation 2 Improvements include a new aluminum guide rod, reducing the overall weight.  Heavier masses translate to more buffering mass and reduced chance of bolt bounce.  There’s now full correspondence between silent captured spring masses and the H1, H2, and H3 buffers.  The interchangeable buffers allow conversion between AR15 and AR10 models, and vice versa.

The JPSCS2-10 is designed to work in standard 7-inch M16/M4-length buffer extension tubes on .308 AR-type rifles like the DPMS LR-308. Armalite .308 rifles, likewise, use these standard M16 extension tubes with rifle-length stocks, so this unit will function normally when installed with the supplied spacer. However, Armalite’s .308 carbines use a slightly longer, non-standard carbine extension tube. The JPSCS2-10 can still be used with these extension tubes by installing the spacer, which must be modified to fit. Alternately, the system will function readily if the longer Armalite carbine tube is replaced with a standard 7-inch .223 carbine extension tube.

The JPSCS2-10 is not compatible with the HK MR762, the Sig Sauer 716, or the Rock River Arms LAR-8 because of its longer bolt stroke and subsequently longer extension tube.
