RCBS 28007 6mm ARC Small Base Die Set

RCBS 28007 6mm ARC Small Base Die Set

The RCBS AR Series die set is purpose-built for reloaders working with modern semi-automatic rifles. This two-die set combines the precision you need with the reliability AR-platform shooters demand.

Key Features

• Small Base Sizer Die: Sized specifically for semi-automatic firearms, this die ensures your reloaded cartridges will chamber reliably in AR-platform weapons. The small base design reduces case diameter slightly more than standard dies, accounting for the tighter tolerances of modern rifle actions.
• Taper Crimp Seater Die: Applies a taper crimp rather than a roll crimp, which is the correct approach for bottleneck cartridges used in semi-automatic rifles. This crimp style provides consistent bullet seating without deforming the case mouth excessively.

Why It Matters

If you're reloading 6mm ARC ammunition for your AR-15 or similar platform, this die set removes the guesswork. The small base sizing guarantees your rounds will chamber smoothly, shot after shot. Whether you're a progressive reloader or working single-stage, these dies deliver the consistency serious shooters expect from RCBS.
