REMOVAL, INSTALLATION AND
TRIMMING INSTRUCTIONS FOR
MAGNUM® LINERS
NOTE: The variation in cable lengths prevents the
interchangeability of liners. Once a liner has
been cut for a particular gun, it should not be
installed in another gun, unless it can meet the
liner cut off length requirement. Liners are
shipped with the jacket of the liner extended
the proper amount.
