J P Enterprises AR-15 Silent Captured Spring Gen 2 H2 w/ Alt Spring Pack

Overview

JP Enterprises AR-15 Silent Captured Spring Features The Gen 2 AR-15 Silent Captured Spring introduces an aluminum guide rod that cuts overall system weight compared to previous versions while maintaining the structural integrity needed for reliable long-term function across thousands of cycles. The H2 configuration provides two tungsten weights and one steel weight delivering a heavier buffering mass profile that slows bolt carrier velocity and reduces the risk of bolt bounce on suppressed short-barreled piston-operated and select fire platforms where standard buffer weight is insufficient for optimal cycling. Full correspondence between JP Enterprises SCS masses and H1 H2 and H3 buffer designations gives shooters a clear and consistent tuning reference when adjusting mass configuration and interchangeable buffers allow conversion between AR-15 and AR-10 models for shooters running both platforms. The included Alternate Spring Pack provides five calibrated spring rates from lightest to heaviest identified by color coding for fast visual reference during installation and live-fire tuning allowing shooters to select the spring rate that delivers the best cycling performance for their specific host configuration without the need for an adjustable gas block. The drop-in design requires no permanent modifications to the host rifle and fits both M4-style collapsible stock buffer tubes and using the included spacer the longer tubes used with fixed rifle stocks making the AR-15 Silent Captured Spring compatible with virtually any AR-15 platform configuration. The combination of the custom-ground buffer spring and JP Enterprises LMOS buffer eliminates the characteristic metallic noise of conventional buffer springs delivering a noticeably smoother and quieter cycling experience that shooters immediately recognize on the first round fired.
