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

Standard Version

This standard version of the XS Silent Captured Spring is built with one steel mass and one tungsten. It is suitable for most standard rifle configurations. For suppressed rifles in need of more mass regulation, choose the JPSCS2-XS-H.


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.
