The JP Enterprises Silent Capture Spring (Generation 2) for AR-15 rifles.

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

JP Enterprises patented Silent Captured Spring maintains all the benefits of thier 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 JPSCS2-15 will not function with older Primary Weapon Systems (PWS) brand bolt carriers. The design of the carrier will prevent the rifle from cycling.
