The JE Machine AR-15 Silent Recoil System is at the forefront of AR buffer technology. Our system is a drop-in replacement for the traditional AR-15 carbine spring and buffer. This revolutionary patented one-piece assembly eliminates many of the risks of other “cap screwed” recoil systems on the market while providing a reduction in buffer noise and felt recoil. Our PS-BFSC4 is constructed from high-strength 4140 steel. This system is truly a testament to our ingenuity and is a must-have for new and veteran shooters alike.

  • Self-contained & drop-in design for easy installation
  • Reduce felt recoil
  • Precision machined high-strength 4140 steel
  • One-piece design for improved reliability
  • For use with carbine buffer tubes only
  • Weight 10.1oz

IMPORTANT: This will only work on a .223 / 556


1. Start with separating your lower and upper receiver
2. Remove your standard buffer components. (Buffer and Buffer Spring)
3. Simply slide in the Silent recoil spring into the buffer tube with the Baseplate, the smaller and lighter end first. The heavier weighted side should be at the head of the buffer tube where it would contact your bolt carrier group once the rifle is re-assembled.
4. Lastly, Re-attach your upper receiver to your lower receiver.

Note: The Silent Recoil Spring system doesn’t require the Buffer Spring Detent and it is optional for the user to remove the Detent for an even easier installation.

    Put one in my CMMG 5.7 banshee to see if I could get the godawful twang out of the buffer tube when fired and not only do it solve that issue the recoil impulse was a lot smoother!!
