JP Enterprises Standard Buffer Gen 2 Silent Captured Spring Builder w/Alternative Spring Pack

The Gen 2 drop-in captured spring recoil system revolutionizes the AR shooting experience by offering a smoother and quieter operation without requiring permanent modifications. This advanced system includes a precisely balanced, custom-ground buffer spring combined with the JP LMOS buffer, which effectively minimizes friction and vibration. It eliminates the common "spoon over a cheese grater" noise associated with traditional springs and buffers. Designed for adaptability, it fits buffer tubes for both M4 style collapsible stocks and, with the provided spacer, can also accommodate longer tubes for fixed rifle stocks. For those interested in customizing their setup, the Auxiliary spring Rate kits for the JP Silent captured spring allow for device personalization to suit specific rifles. While the default spring delivers excellent performance across various configurations, a simple disassembly and reassembly with a different spring rate can enhance performance, particularly in rifles without an adjustable gas block. Elevate your AR performance with the Gen 2 drop-in captured spring recoil system, where precision engineering meets User-friendly customization.The newly designed aluminum guide rod reduces the overall weightIncludes (3) stainless steel weightsIncreased mass results in greater buffering capacity and a higher likelihood of bolt bounceComplete correspondence exists between SCS masses and the H1, H2 and H3 buffers
