Description

RCBS Universal Primer Arm Assembly #09550

The RCBS Universal Primer Arm—2 is designed to seat primers quickly and accurately. Primer plugs and covers for large and small rifle and pistol primers are supplied. Size changes are quick and simple, requiring less than 60 seconds. The arm is compatible with the Rock Chucker® II, JR, Reloader Special, and the majority of C presses.

Note: This product is not compatible with the Rock Chucker Supreme.
 

Best Suited For

  • Reloaders using RCBS single-stage presses, such as:
    • Rock Chucker / Rock Chucker II / JR
    • Reloader Special
  • Users who want a complete replacement priming arm, not just small parts
  • Reloaders working with both small and large primers (one kit handles both)
  • Those who prefer on-press priming instead of separate hand priming tools

When To Use It

Use this assembly when:

  • Your existing priming arm is missing, damaged, or unreliable
  • You want to upgrade or replace the entire priming mechanism rather than individual components
  • You are experiencing issues like:
    • Primers feeding incorrectly (e.g., double feeds)
    • Misalignment or inconsistent seating
  • You want quick switching between small and large primers (no separate arm needed)

💡 Size changes are fast—typically under a minute by swapping primer plugs/sleeves.

FAQs

A: No. It is not compatible with that model—use the appropriate RCBS priming system instead.

Q: How easy is switching primer sizes?
