Double Alpha Mr. Bulletfeeder Pro Conversion Kit

You can use your Doubla Alpha Mr. Bulletfeeder PRO for more than just one caliber, switching over quickly and easily with the help of the readily-available conversion kits. These kits include all the parts needed to switch your bullet feeder from one caliber to the next in a matter of minutes.

A Mr.Bulletfeeder PRO pistol conversion kit includes a PRO collator plate, a full PRO dropper assembly and an expanding powder funnel. The Rifle conversion kit includes the PRO collator plate, a full PRO dropper assembly, and a small output spring assembly. No powder funnel is included with the rifle calibers, as those cannot be used due to the small size of the case mouth.

Notes:

• All pistol calibers use the same output tube, lead spring and spring adaptor cap. So this assembly is not included in the conversion kit – as you will not need a second one when changing pistol calibers.
• The rifle calibers too share the same output assembly, and so when converting from 223 to 308, the same output assembly is used.
• If you intend to buy a conversion kit to convert a rifle unit to a pistol caliber, you must purchase the output assembly required, in addition to the conversion kit
