The Mr.BulletFeeder Optimization Kit is a set of parts to make setting-up and changing  calibers in your Mr.Bulletfeeder faster and easier than ever!

This clever kit of parts includes the following parts and features:

• A set of 8 nose-guide spacers (with handy holder), numbered for use  with over 70 popular calibers/bullet profiles. Use the included guide  to select the right spacer for  your caliber and bullet profile, pop in  the spacer under the nose-guide, and you will instantly have the optimum  nose-guide position for that bullet!
• Two adjustment guides for setting the correct angle of the bullet collator, for both the new and old style hangers.
• A new and improved pistol flip-ramp which eliminates the need to adjust the ramp position when changing calibers.
• A newly designed rifle bullet ramp, perfect for all length projectiles.
• A set of 3 large gnarled thumb-screws to replace the original  screws for the nose-guide, flip-ramp and output tube in the  Mr.BulletFeeder, eliminating the need to use a tool to make adjustments.

Note: The MBF optimization kit will NOT work with Mr.Bulletfeeder PRO model.
