Possum Hollow O-Ring Replacement Kit 308 Calibre

The O-rings on your Possum Hollow bore guides and Solvent Ports should be replaced occasionally because solvents and use eventually wear them out. Four sizes of O-rings are used throughout, so having some spares on hand is not expensive. The 222 and 223 family of guides and the 17 calibre guides do require the O-ring installation tool included in the O-ring kits. The two larger size O-rings can be installed fairly easily without the tool, though the kits include the tool for almost no additional charge over the 10 O-rings. All three O-ring sizes are available separately in 5-packs.
