Have you ever thought about owning a silent AR15? Okay, no firearm is truly silent, but it is possible to reduce operational noise. For a quieter shooting experience, consider the JP Silent Captured Spring Gen 2. After having been a company for so many years now, JP has earned the respect and trust of gun owners from all backgrounds – military, civilian, law enforcement and competitive shooters. The company is known for its high-quality products and its strong commitment to customer satisfaction.

The JP Silent Captured Spring system is a novel invention that decreases the operational noise of your rifle. This self-contained unit is designed to replace the traditional buffer and spring system. The highly-polished components of this assembly offer extraordinarily smooth and quiet operation, hence the name "silent." Although this system is specifically designed for use with the low-mass bolt carrier and the adjustable gas system by JP, it is also easily compatible with standard components. This product also includes a spacer to accommodate A1/A2 fixed stock buffer tubes. You can also switch out the spring to custom-tune your rifle.

The Silent Captured Spring buffer system will dramatically reduce operational noise when used with a tuned gas system. This product is offering you reduced recoil and also makes your shooting experience more enjoyable. If you want a product that diminishes and also smoothens your shooting experience, JP Enterprises' Silent Captured Spring AR-15 Buffer System will certainly do the trick.

H2 Buffer Version is recommended to use with:

  • Short-barreled rifles (SBRs)
  • Suppressed weapons
  • Rifles recommended to use an H2 buffer
  • Select-fire AR-15s
  • Piston-operated AR-15s

*This Silent Captured Spring System will not function with older Primary Weapon Systems (PWS) bolt carriers. The design of the carrier will prevent the rifle from cycling.
