Note: 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.

The JP Enterprises Gen 2 Silent Captured Spring Standard Version is a premium upgrade for AR-15 buffer and spring systems, engineered to deliver ultra-smooth cycling and eliminate the gritty “cheese grater” sound typical of standard buffer components. Designed for gas-operated AR-15 rifles, this all-in-one buffer and spring assembly incorporates JP’s patented Silent Captured Spring technology, offering a refined shooting experience through reduced friction, minimal vibration, and unmatched quietness. At just 5.3 oz. total weight with a 2.9 oz. reciprocating mass, it’s ideal for replacing a standard buffer of the same weight and comes with a spacer for compatibility with both carbine- and rifle-length buffer tubes. Whether you’re optimizing for competition, defense, or range use, this silent buffer system enhances feel, consistency, and performance in every shot.
