Top takeaways

  1. O-rings in Sinclair bore guides and related tools wear out and should be replaced occasionally.
  2. The kit includes three sizes of O-rings and an O-ring installation tool for the 17 caliber and 222/223 family guides.
  3. O-rings are available separately in 5-packs, but the kits offer extra value with the included tool.
