Second 550 primer system

If i wanted a complete second automatic primer system for my 550B, would the DILLON RL 450 UPGRADE AUTO PRIME SYST.
Stock Number: 20055 be the way to go? I would like to have a second complete system to make switch overs between primer sizes simpler.

You should already have the primer slide and magazine tube you need for the other primer size. So all you really need is the complete primer feed housing, stock #20263.

RE: Second 550 primer system

Hi, this sounds like a great idea. But if you look at your RL550B schematic do we need just part 528? To me it looks like if you had 581 and bolt 549 on the extra housing it may make it faster to switch. I'm going to order one. Just let me know for sure which parts.
Thanks Mike White

RE: Second 550 primer system

The part numbers you are using are obsolete since 1998. The primer feed body, stock#20263, includes all of those parts.
