The Hoppe’s Universal Bore Guide (Hoppe’s part no. UBG) keeps solvent from dripping into the action while also preventing excessive cleaning rod contact with the rifling lands closest to the chamber. That protection matters most for precision shooters, since repeated rod contact right at the throat can gradually wear the most critical part of the bore. Three interchangeable chamber tips let this single guide fit calibers from .17 all the way to .416, and an aluminum action collar fits .695/.700-inch diameter bolt actions of any action length.
