Product Summary
The JP Enterprises Alternate Spring Pack is an essential tuning kit designed specifically for the JP Silent Captured Spring (JPSCS) recoil buffer. This kit allows shooters to customize spring tension to optimize rifle performance, which is particularly useful for builds lacking an adjustable gas block. By choosing the correct spring rate, you can prevent the buffer head from bottoming out or ensure the bolt carrier locks back reliably on the last round. The pack includes five different spring options, ranging from 80 to 100, to accommodate various configurations and specific hardware like ambidextrous bolt catch extensions.
