JP Enterprises GEN 2 AR15 Silent Captured Spring Builder Kit with 5 Alternative Spring Pack -Standard Version

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 we’ve worked ardently to eliminate.  After years of specially selecting buffer tube manufacturers based on the quality of their tubes’ interior finish, they 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 Enterprises pursuit of perfection didn’t stop with springs though and led ultimately to the creation of the JPSCS Silent Captured Spring (patented) in 2012. Maintaining all the benefits of our 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, and both the AR-15 and AR-10 versions of the JP Silent Captured Springs are functional in rifle- and carbine-length operating systems. The AR-15 version fits and functions in any gas-operated AR-15 variant, regardless of caliber and the AR-10 version should fit and function in any large-frame AR-10-type platform. The JPSCS is not compatible with any 9mm AR variant or any blowback system using a solid (weighted) carrier.

Standard Version

Includes SCS unit, five alternative weight springs and spacer to allow for installation in both carbine- and rifle-length buffer tubes.

****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.
