GEN 2 Silent Captured Spring (patented) for Maxim CQB stock equipped rifles

Heavy Version

This heavy version of the XS Silent Captured Spring is built with two tungsten masses for a heavier deadblow effect. It is suited to suppressed or other rifles in need of more mass regulation.


The JPSCS2-XS will not function with older Primary Weapon Systems (PWS) bolt carriers. The design of the carrier will prevent the rifle from cycling.

The overall length of the JPSCS2-XS is 5.65" and is designed specifically to fit the the Maxim Defense CQB.
