JP Enterprises – 9mm AR Silent Captured Spring - Enhanced - GEN 2

$184.95
SKU: 
4434

9mm AR Version

The 9mm Silent Captured Spring is a drop-in component that softens recoil and reduces cycling noise and vibration in your 9mm carbine. The result is a refined rifle that's a pleasure to shoot. Paired with our 9mm bolt assembly, you have the most reliable 9mm operating system available.



JP Enterprises – 9mm AR Silent Captured Spring - Standard - GEN 2

$159.95
SKU: 
4433

The 9mm Silent Captured Spring provides the same improvements of smoother operation and reduced cycling noise as our gas gun models.

Compatibility:

The 9mm SCS requires an open channel in your 9mm bolt assembly for the guide rod to pass during fire. For most bolts, this will require you to remove the pinned-in central mass. To function with the SCS, this central mass must be removable, and the bolt must still be at its full length without it.
