Maxim Defense CQB JP Silent Captured Spring Heavy Buffer System
The Maxim Defense CQB JP Silent Captured Spring Heavy Buffer System is a precision-engineered recoil management solution built exclusively for use with the Maxim Defense CQB Stock System, delivering smoother cycling and dramatically reduced felt recoil noise on your AR-platform rifle.
- Manufactured exclusively for the Maxim Defense CQB Stock System
- JP Silent Captured Spring design eliminates buffer rattle during operation
- Heavy buffer weight tuned for suppressed and standard AR-15 configurations
- Requires a JP-modified BCG with open channel for guide rod clearance
- Improves cycling consistency and reduces carrier bounce under fire
- Compatible with JP Enterprises modified bolt carrier group assemblies
Who This Is For
This system is purpose-built for serious AR-15 shooters who are already running or building around the Maxim Defense CQB Stock and want the ultimate in recoil management and operational quietness. It's ideal for competitive shooters, home-defense builds, and suppressor-equipped rifles where smooth, reliable cycling is non-negotiable. Because it requires a JP Enterprises modified bolt carrier group, it's best suited for experienced builders comfortable speccing their BCG accordingly.

Frequently Asked Questions
Will this buffer system work with any AR-15 stock or buffer tube?
No — the Maxim Defense CQB JP Silent Captured Spring Heavy Buffer System is designed exclusively to work with the Maxim Defense CQB Stock System. It is not compatible with standard mil-spec buffer tubes or other aftermarket stocks. Attempting to use it with an incompatible stock can result in improper function or damage to your rifle.
Do I need a special bolt carrier group to use this system?
Yes. The JP Silent Captured Spring uses a guide rod that must pass through an open channel in the bolt carrier group during the firing cycle. This modified BCG is not a standard mil-spec part and must be sourced separately from JP Enterprises. Make sure you have the correct JP-modified BCG before installing this buffer system.
Why choose a heavy buffer for my AR-15 build?
A heavy buffer slows the rearward travel of the bolt carrier group, which helps reduce felt recoil, limit carrier bounce, and improve reliability — especially on rifles running suppressed or with overgassed configurations. Combined with the JP Silent Captured Spring's noise-dampening design, this system provides noticeably smoother and quieter cycling compared to a standard buffer and spring setup.
