Maxim Cqb Buffer Jp Scs Hvy

The Maxim CQB Buffer JP SCS Heavy is a specialized captured spring system designed exclusively for integration with the Maxim Defense CQB Stock platform. This component pairs JP Silent Captured Spring technology with Maxim Defense's compact stock system, delivering a purpose-built solution for close-quarters battle configurations and short-barreled AR platforms where recoil management and compact profile are critical operational requirements.

The captured spring design eliminates the traditional spring and buffer tube rattle, providing consistent performance across firing cycles while reducing auditory signature during operation. The heavy buffer weight is engineered to optimize cycling reliability in short-barrel configurations where bolt velocity may be reduced compared to full-length setups. Proper function requires a compatible bolt carrier group featuring an open channel to accommodate the guide rod during fire—JP Enterprises manufactures BCGs specifically modified for this purpose. Weighing 0.44 lbs and measuring 1.75 x 1.75 x 8.5 inches, the component integrates cleanly within tight receiver envelopes without sacrificing durability or shot-to-shot consistency.

This system serves operators and shooters building or maintaining short-barreled AR platforms optimized for CQB environments, patrol carbines, or precision short-range work where standard buffer tubes prove impractical. The Maxim CQB stock platform with this buffer assembly enables exceptional modularity and trigger control in confined spaces where traditional length-of-pull and recoil characteristics must be carefully controlled. Serious builders prioritizing performance, reliability, and compatibility with dedicated platform ecosystems will find this component addresses the specific engineering demands of modern compact tactical rifles.
