|
These target holders are designed to work with
the Brunson Invar System. On one end, a 3/8"–24 external thread mates to our standard
Invar System tubing. The other end provides a
slip-fit holder for targets having either a 6mm
or a 1/4" diameter shank. A brass thumbscrew
allows you to secure the target without
gouging the shank. Several different
configurations of this target holder are
available. Using the table below, choose
desired values for A (offset) and B (bore
diameter). This item is supplied with a spare
thumbscrew. You may wish to read about
our other Invar System Components as well.
