JP Rifles Gen 2 Silent Spring System for AR10 Heavy H2 .308

Gen 2 Silent Spring System Features

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. What’s more, the spring is removable from the assembly for custom tuning, and both the AR-15 and AR-10 versions of the JP Silent Captured Springs are functional in rifle- and carbine-length operating systems. The AR-15 version fits and functions in any gas-operated AR-15 variant, regardless of caliber. The AR-10 version should fit and function in any large-frame AR-10-type platform based on the AR-10 or LR-308 platform. The JPSCS is not compatible with any 9mm AR variant or any blowback system using a solid (weighted) carrier.
