RCBS Expander-Decapping Unit 223 Remington/5.56mm

The RCBS Expander-Decapping Unit for 223 Remington and 5.56mm NATO is a factory replacement part for RCBS sizing dies. It contains the expander rod, expander ball, and decapping pin used to remove the primer from a spent case and expand the neck of bottleneck cartridges during resizing. The unit is precision machined to help keep the decapping pin and expander concentric with the die body.

Keeping a spare decapping unit on hand lets you continue a reloading session if the original is damaged. Because it is a factory part, it is intended to match the fit and function of the original RCBS die components. The unit is listed for use with 222 Remington, 223 Remington, 22-250 Remington, and 5.56x45mm NATO brass, among other calibers in the RCBS line.
