Maxim Defense Industries
The Maxim Defense Industries Standard JP Silent Captured Spring System is a precision AR-15 bolt carrier upgrade designed for shooters who want noticeably smoother cycling and reduced operational noise. Built by JP Rifles exclusively for Maxim Defense CQB stocks, this captured spring system replaces your standard buffer setup and eliminates the friction that typically comes with conventional spring assemblies—resulting in a quieter, more refined shooting experience whether you're running drills on the range, conducting defensive training, or working through precision shooting scenarios.
The key advantage here is the engineering: instead of loose components rattling around in your buffer tube, the captured spring system keeps everything contained and synchronized. This design reduces friction at critical cycling points, which translates to less mechanical noise as your bolt travels back and forth. You get a smoother feel on the gun, more consistent operation, and audible quietness without sacrificing reliability or adding complexity to your rifle.
Maxim offers this system in a Standard weight version, which provides the equivalent performance of a 3.3 oz buffer weight. If you're running a select-fire platform or need heavier spring pressure, the JP Heavy version is also available and delivers the equivalent of a 4.0 oz buffer. This gives you tuning flexibility depending on your specific rifle configuration and ammunition load, so you can dial in the exact cycling characteristics your setup demands.
| Brand | Maxim Defense Industries |
| Product Type | Captured Spring System |
| Designed For | Maxim Defense CQB Stock |
| Weight Class | Standard (3.3 oz equivalent) |
| Manufacturer | JP Rifles |
| Platform | AR-15 |
The JP Silent Captured Spring System is designed specifically for the Maxim Defense CQB Stock. Verify compatibility with your current setup before ordering.
Unlike traditional buffer assemblies where the spring and buffer are separate and can create friction and noise, this captured spring system keeps all components synchronized and contained. That design eliminates friction points, resulting in smoother cycling and noticeably quieter operation.
Yes. This listing is for the Standard weight version (equivalent to 3.3 oz buffer weight). Maxim Defense also offers a Heavy weight version that's equivalent to a 4.0 oz buffer and is suited for select-fire platforms.
The primary benefit of the Silent Captured Spring System is smoother cycling and reduced noise. While the engineering affects how the bolt carrier cycles, the main performance gains are in consistency and sound signature rather than recoil reduction.
