JP AR15 Silent Captured Spring Builder Kit – Gen 2

JPSCS2-15K | AR15 Silent Captured Spring Standard 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 AR15 Silent Captured Spring Builder 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 AR15 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. However, it 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 h2, H2, and H3 buffers. The interchangeable buffers allow conversion between AR15 and AR10 models, and vice versa.
