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

9mm Version

This alternative configuration of the XS Silent Captured Spring is built with special slider to accommodate three tungsten masses. It is suitable for muse with 9mm carbine systems, which require more mass regulation for their blowback operating systems.


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.
