Sco O-ring Pack

SilencerCos O-Ring Pack for their rimfire suppressors contains replacement O-rings for a Sparrow, Warlock II, or Spectre II silencer to keep it running at its maximum sound suppression capability. The O-rings are a critical part because they contain blast and debris to keep your suppressor operating quietly and cleanly - the way its supposed to.
