https://www.youtube.com/embed/tojNJ5DhZJY?rel=0 I was tired of using a wrench & a screwdriver to adjust my RCBS seating dies. So I decided to create my own locking wheels & micro adjustment knob. This auction is for all 4 pieces. They are printed at high quality. All pieces thread on to dies, so they can be removed easily if needed. This set will work with the RCBS 3 die pistol set. These are 3d printed at high resolution(200 micron). These have also been printed small enough that they will still fit in the factory storage box. I have included a color guide. If you would like any other color besides green, please make a note of the color number during checkout. Does not come with the die itself, just the wheels & the micro adjustment.
