An Additional Front End makes stylus size change-over quick and easy!
Shown on the right is a ME (or CP) front end with a 2" bushing. Below it is shown 3" and 4"  Paleo Tools styli.
This is the 3" stylus in the front end and bushing.
This is the 4" front end in the bushing. If you have only one front end this is the only easy change out. If you add another front end to your tool kit, you can leave the short bushing in one, and the long bushing in the other one, making change-out much quicker and easier.
Cost - $73.00 (plus shipping) for the front end (price does not include the bushing or stylus) Makes for a single minute size change without needing 2 complete tools!
