RCBS AR Series Small Base 6mm ARC Full Length Sizing, Bullet Seating 2 Die Set with Taper Crimp

Overview

The RCBS AR Series 2-Die Set for 6mm ARC includes a full-length small base sizing die and a bullet seating die with a built-in taper crimp. The small base sizer ensures cases are set to SAAMI minimum cartridge dimensions, decaps the shell, expands the neck, and guarantees reliable rechambering and feeding in AR-platform semi-automatic firearms. The sizing die is vented to prevent trapped air or excess lubricant from damaging cases, while the seater features a unique 7-degree crimp angle designed for autoloading rifles to secure bullets against recoil and avoid case damage.
