Improved Silent Capture Spring To Reduce Recoil On AR-15 Platforms

The JP Silent Captured Spring is a drop-in module replacement for the traditional buffer and buffers spring components of the AR-15 platforms. It helps the rifle’s operation by eliminating the raspy scraping of the buffer spring against the interior of the extension tube and yields a virtually silent cycling action with a dramatic reduction in friction and vibration during live fire.

SCS Buffer Retainer Pin

Because the insertion and removal of the Silent Captured Spring are very difficult with a standard buffer retainer pin, we recommend removing it when installing your SCS. This leaves the SCS “free-floating” in the buffer tube. While this isn’t a problem when the receivers are closed, some shooters find it objectionable. In this case, we have a custom Silent Captured Spring Buffer Retainer Pin and Spring available to retain the SCS without the snagging caused by the Mil-spec design.

Includes spacer to allow for installation in both carbine and rifle-length buffer tubes.

Recommended Use:

  • Short-barreled rifles (SBRs)
  • Suppressed weapons
  • Rifles recommended using an H2 buffer
  • Select-fire rifles
  • Piston-operated rifles
  • Weight: 6.9 oz.


  • The JPSCS2-15 will not function with older Primary Weapon Systems (PWS) bolt carriers. The design of the carrier will prevent the rifle from cycling.


  • Eliminates buffer & spring noises
  • Fit both carbine and rifle buffer tubes (comes with a spacer for fixed stock buffer tubes)
  • New aluminum guide rod reduces overall weight
  • Heavier masses translate to more buffering mass and chance of bolt bounce
  • Full correspondence between SCS masses and H1, H2, and H3 buffers
  • Interchangeable buffers allow conversion between AR-15 and AR-10 models



  • Guide Rod: Aluminum
  • Buffer Weights: Tungsten and Steel


  • Silent Captured Spring System: 7″
  • Spacer: 2.7″

Weight: 5.3 oz.
