The Lee Collet Neck Sizer Die is a single collet neck-sizing die intended for use with .223 Rem/5.56 NATO cartridge cases. The collet squeezes the case neck against a precision mandrel to improve concentricity and reduce bullet runout. This die sizes only the neck and requires no lubrication, making it suitable for reloaders focused on consistent neck tension and bullet alignment.
