JP Enterprises Silent Captured Recoil Buffer Spring Gen 2 9mm AR-15

JP Enterprises Silent Captured Recoil Buffer Spring Gen 2 9mm AR-15 The “spoon over a cheese grater” sound emitted by modern sporting rifles whenever they’re charged or fired has always been one of the AR platform’s ugly blemishes and one JP Enterprises worked ardently to eliminate. After years of specially selecting buffer tube manufacturers based on the quality of their tubes’ interior finish, JP Enterprises opted to design and produce their own action springs with a perfect centerless-ground and precision-polished outside diameter. These JP Custom Buffer Springs are an inexpensive way to see exactly why they have a reputation for having the quietest, smoothest rifles on the market. JP's pursuit of perfection didn’t stop with springs though and led ultimately to the creation of the patented Silent Captured Spring in 2012. Maintaining all the benefits of their polished buffer springs and proprietary LMOS buffer, this combination buffer-spring assembly eliminates the friction of standard buffer components resulting in outstanding smoothness and sound abatement. What’s more, the spring is removable from the assembly for custom tuning. Note: 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.
