JP Enterprises H2 Buffer Gen 2 Silent Captured Spring Builder w/Alternative Spring Pack

Upgrade your AR-platform with the Gen 2 drop-in captured spring recoil system, designed to enhance your firearm's performance with smoother operation and reduced noise. This innovative system eliminates the harsh "spoon over a cheese grater" sound typical of conventional springs and buffers thanks to its meticulously balanced, custom-ground buffer spring paired with the JP LMOS buffer. Experience a significant reduction in friction and vibration, ensuring a quieter and more efficient shooting experience. The Gen 2 system is versatile, fitting both M4 style collapsible stock buffer tubes and, with the included spacer, the longer tubes for fixed rifle stocks. The H2 buffer, heavier than standard springs, incorporates two Tungsten weights alongside a steel weight, bringing the total weight to approximately 4.7 oz. This configuration is ideal for short-barreled rifles, suppressed firearms, select fire rifles and piston-operated rifles, providing enhanced stability and performance. For those seeking to fine-tune their setup, the Auxiliary spring Rate kits for the JP Silent captured spring offer customizable tuning options. While the default spring is optimized for a broad range of configurations, users can achieve peak performance by adjusting the spring rate, especially beneficial for rifles lacking an adjustable gas block. The heavy spring system Version, featuring Tungsten weights, is specifically recommended for short-barreled rifles, suppressed weapons, rifles with an H2/H3 buffer, select fire rifles and piston-operated rifles. Elevate your shooting experience with the Gen 2 drop-in captured spring recoil system, where precision engineering meets unparalleled performance.The newly designed aluminum guide rod reduces the overall weightIncreased mass results in greater buffering capacity and a higher likelihood of bolt bounceComplete correspondence exists between SCS masses and the H1, H2 and H3 buffersIncreased mass has been incorporated into both the AR-10 and 9mm models to enhance their functionality and performance
