This priming system is made to be used with our Co-ax XL press, it includes assemblies for BMG Primers as well as Large Rifle Primers (there is no option for small rifle primers on this press).

This system mimics what is on our standard Co-ax press using adjustable jaws and a controlled stop built into each primer seater assembly that will assure a consistent stop each time.

There is a lot of value in this tool considering there are very few priming options for 50 BMG.
