Ordering by number: this is R047971, also listed as 3310190078, the Chicago Pneumatic front head spring. It is the business end of the breaker it locates the tool steel and absorbs the impact reaction, so bore wear here shows up as a loose, rattling shank.
It appears on the CP 1230 1230S 1230SVR Paving Breaker and CP 1230 SPDR 1230S SPDR Spike Driver breakdown. Worth matching the reference number on the diagram against your own machine before you order the same part number can sit in more than one position.
Everything else on that machine is one page away on the parts diagram hub; complete tools are on the Chicago Pneumatic tool range. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
