The RCBS Primer Catcher Front Suit Rock Chucker New Model (Model R109145) is a genuine factory replacement part designed to maintain a clean and orderly reloading bench. As an essential component of the spent primer disposal system, this front tray catches and retains spent primers and carbon residue as they are punched out of fired cartridge cases during the resizing and depriming stages. Molded from durable polymer, it fits seamlessly onto the press frame to prevent debris from falling onto the floor or workspace.

Key Features

• Targeted Spent Primer Collection: Captures spent primers directly below the ram during the decapping stage, keeping your workspace free of carbon and metal debris.
• Two-Piece System Integration: Serves as the front portion of a dual-piece catcher assembly, locking securely to the press frame when paired with the rear piece and locking clip.
• Contoured Fit: Precision-molded to match the modern O-frame geometry of the Rock Chucker Supreme press, ensuring a snug fit that stays in place during high-force stroke cycles.
• Easy Detachment: Easily slides or unclips from the assembly for fast, hassle-free emptying into a waste bin.

Who is the RCBS Primer Catcher Front Suit Rock Chucker New Model for?

• RCBS Rock Chucker Supreme owners — restores the original spent primer disposal system of their RC IV press with an OEM part that provides a physical storage capacity of 50 to 100 spent primers before requiring manual emptying.

Less suitable for: high-volume reloaders processing thousands of rounds per session, as they will quickly exceed the capacity threshold of 50 to 100 primers; such reloaders are better served by progressive reloading presses or aftermarket drop-tube systems that route spent primers continuously into a larger external waste bin. It is also not compatible with vintage Rock Chucker I, Rock Chucker II, or Reloader Special presses, which feature a different frame geometry requiring legacy wrap-around clip-on tray designs.
