Who This Is For
This system is purpose-built for shooters running a Maxim Defense CQB Stock who demand reliable, smooth cycling in a compact or short-barreled AR-15 build. It is ideal for competitive shooters, home defense builds, and duty-use rifles where minimizing recoil, noise, and mechanical rattle is critical. Note that this system requires a modified bolt carrier group with an open channel for the guide rod — available separately from JP Enterprises.

Frequently Asked Questions
Will this JP Silent Captured Spring System work with any AR-15 stock?
No. This system is manufactured exclusively for use with the Maxim Defense CQB Stock System and is not compatible with standard carbine, rifle, or other pistol-length buffer tubes. Attempting to use it with a different stock or buffer tube could result in improper function or damage to your firearm.
Do I need a special bolt carrier group to run this system?
Yes. The JP Silent Captured Spring System uses a guide rod that must pass through an open channel in the bolt carrier group during the cycling process. You will need a modified BCG with an open-channel design, which is available directly from JP Enterprises. Standard bolt carrier groups are not compatible with this system.
What are the benefits of a silent captured spring over a standard buffer and spring?
A silent captured spring system consolidates the buffer and recoil spring into a single self-contained unit, eliminating the loose spring rattle associated with traditional setups. This results in reduced felt recoil, quieter operation, and more consistent cycling — particularly valuable in compact and short-barreled AR-15 configurations where reliable function is critical.
