The JP Enterprises JPSCS2/VMOS Replacement O-Rings With Spacer Shim 12PK is a dedicated maintenance kit for JP Silent Captured Spring systems and Variable Mass Operating System (VMOS) bolt carriers. This pack includes twelve precision O-rings along with a spacer shim and related hardware, giving shooters the correct components to restore proper sealing and function when factory rings begin to show wear.
Ideal for owners running high round counts, especially in 9mm carbines where O-ring wear can appear around the 5,000-round mark, this kit helps keep cycling smooth and consistent. Use it during routine inspections to replace any frayed, cracked, or lost rings and to maintain reliable operation at the range, in competition, or during training sessions. The thoughtful design reflects JP Enterprises’ reputation for careful engineering and attention to detail in performance-focused rifle components.
