Description
The RCBS AR Series Small Base Die Set is purpose-built for handloaders running 6.5 Creedmoor through AR-platform semi-automatic rifles. This 2-die set pairs a Small Base Sizer Die with a Taper Crimp Seater Die to produce loaded ammunition with the dimensional consistency and crimp integrity that semi-auto actions demand.
The Small Base Sizer is engineered to size brass slightly under SAAMI specifications, giving you the tight case dimensions needed for reliable feeding and chambering in AR-style semi-automatic rifles. The companion Taper Crimp Seater Die features RCBS’s signature 7-degree taper crimp, which firmly seats the bullet without over-crimping and produces a properly finished cartridge ready for magazine feeding.
Both dies are threaded 7/8×14, the industry standard, so they mount in any single-stage or turret press that accepts standard reloading die threads. A shell holder cap is not included with this set.
