RCBS 28007 6mm ARC AR Series Small Base Taper Crimp Die Set

The RCBS 28007 AR Series Die Set is designed for reliable 6mm ARC ammunition preparation, especially for progressive reloading setups and semi-automatic firearms. This two-die set combines a Small Base Sizer Die with a Taper Crimp Seater Die to support consistent sizing, bullet seating, and dependable chambering in AR-platform rifles. The Small Base Sizer Die reduces the case to dimensions that promote reliable rechambering, making it well suited for the cycling and chambering demands of semi-automatic actions.
The Taper Crimp Seater Die seats bullets and applies a controlled taper crimp, helping secure the projectile without excessive case deformation. This combination provides an efficient workflow for reloaders who want to perform essential case preparation and bullet seating with a matched die set. RCBS is known for producing durable reloading equipment designed for repeatable performance, and the AR Series continues that focus with features tailored to modern sporting rifles and similar semi-automatic platforms.
The 28007 die set is a practical choice for reloaders working with 6mm ARC cartridges and seeking dependable operation from their completed ammunition. Its AR Series configuration is intended to support progressive presses while remaining suitable for other compatible reloading presses. Use proper loading data, inspect cases carefully, and follow established reloading practices when preparing ammunition. With its purpose-built sizing and seating functions, this RCBS set provides a streamlined solution for producing consistent 6mm ARC loads for AR-platform firearms.
