- To make the transition easy, the Mr. Bulletfeeder by Double-Alpha conversion kits includes a complete dropper assembly, a custom powder funnel for pistol calibers (this is not included or needed for rifle calibers) and a new collator plate for the caliber of choice. This will allow you to switch your bullet feeder from one caliber to the next in a matter of minutes.
- The spring output tube securely attaches to the top of the dropper by means of the Spring Adaptor Cap, which attaches and disconnects easily from the top of the dropper. The inner threading grips the coils of the spring firmly, preventing any chance of it coming loose during operation, and allows a quick transition from one dropper to the next.
- All rifle calibers (223,30cal) use the same Small output tube assembly, and so when converting from 223 to 308, the same output assembly is used. As previously noted the rifle caliber kits do not include, or need, the custom powder funnel so you will have to supply your own powder funnel.
However – if you intend to buy a conversion kit to convert a rifle unit to a pistol caliber, or from a pistol caliber to a rifle caliber, you must purchase the appropriate output assembly required, in addition to the conversion kit
