The Maxim Defense CQB Buffer using JP Enterprises’ Silent Captured Spring System in the heavy weight (Maxim Defense part no. MXM47571) is manufactured exclusively for use with the Maxim Defense CQB Stock System. This JP Silent Captured Spring System requires an open channel in the bolt carrier group assembly so the guide rod can pass freely during firing, and that modified BCG is available separately from JP Enterprises. It is a purpose-built component rather than a universal buffer, so it is intended for shooters already running or building toward the Maxim CQB stock platform.
