Important Safety Information

RCBS® AR Series Die Sets are a must for progressive reloaders. They feature a Small Base Sizer Die designed for semi-automatic firearms, and a Taper Crimp Seater Die. The Small Base Sizer guarantees the cartridge will rechamber in AR-platform weapons.
RCBS AR Series Small Base Die Set comes with our 7-degree taper crimp seater die, and the sizing die is special in that it sizes the brass smaller than SAAMI specifications. This helps aid greater reliability in semi-automatic rifles like the AR-15 pattern rifle and more. If feeding reliability is a must in your semi-auto - These are the dies for you.
AR Series Small Base Die sets are available for most of today's popular cartridges that are chambered in Semi-Auto rifles including .223 Remington, .308 Winchester, 6mm ARC, 6.5 Grendel, and 7.62x39. The set arrives with printed instructions and in a black box.
The Small Base die sizes the brass down smaller than a standard die. This can increase reliability in your semi-automatic rifles.
The seater die features a 7-degree taper crimp to allow for proper crimping of your ammunition. This helps prevent bullet setback in the brass during feed ramp impact and inside the magazine during recoil. It also provides a smoother transition from the bullet to the brass as the round passes from the magazine into the chamber to avoid hang-ups.
Like all of our dies, AR Series Small Base Dies are made right here in America in our Oroville, California manufacturing facility.
