The Maxim Defense Industries Heavy JP Silent Captured Spring System is a purpose-built replacement for the Maxim Defense CQB Stock, engineered in partnership with JP Rifles to deliver a smoother, quieter cycling experience on your AR-15. If you're running a select-fire platform and want to reduce bolt carrier noise and felt recoil impulse without sacrificing reliability, this heavy-weight captured spring system eliminates the friction and slap that plague standard buffer tube setups.
JP Rifles' captured spring design is an exclusive offering for Maxim Defense stocks. Unlike traditional spring-and-buffer arrangements where components rattle and bind, the captured system keeps everything contained and controlled, translating to noticeably quieter operation as the bolt cycles through its full stroke. The Heavy version delivers the heft you need for full-auto or heavy-recoiling configurations, tuned to match the performance of a 4.0oz buffer weight.
Built for shooters who demand precision and quietness—whether you're training, competing, or running precision drills—this system pays dividends every time you press the trigger. Installation fits directly into your Maxim Defense CQB Stock, so there's no guesswork about compatibility or fitment.

Yes. The Heavy variant is engineered for select-fire platforms and delivers performance equivalent to a 4.0oz buffer weight. If you're running semi-auto only, consider checking whether Maxim also offers a Standard weight option.
By eliminating friction between the spring and buffer, the captured design produces less noise and slap as the bolt cycles. Exact noise reduction varies based on your rifle setup, ammunition, and suppressor use, but most users report noticeably smoother, quieter operation.
We don't have installation details in our specs. Contact Maxim Defense or consult your CQB Stock manual for installation requirements and any necessary tools.
