    JP's pursuit of perfection didn’t stop with springs though and led ultimately to the creation of the JPSCS™ Silent Captured Spring, new for 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 and the AR-10 version should fit and function in any large-frame AR-10-type platform. The JPSCS is not compatible with any 9mm AR variant or any blowback system using a solid weighted carrier.

    Includes spacer to allow for installation in both carbine-length and rifle-length buffer tubes.

    Compatibility
    The JPSCS-AR10 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 the JPSCS-AR10 will function normally when installed with the supplied spacer. However, Armalite’s .308 carbines use a slightly longer, nonstandard carbine extension tube. The JPSCS-AR10 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 JPSCS-AR10 is not compatible with the Rock River Arms LAR-8 because of its longer bolt stroke and subsequently longer extension tube.
