The RCBS 32907 AR Series Small Base Die Set for 6.5 Creedmoor is purpose-built for reloaders who run AR-platform rifles and want ammo that chambers reliably and fires consistently. This two-die set combines the precision and durability RCBS is known for with the specific geometry that semi-automatic rifles demand. Whether you're working up loads for precision shooting, hunting, or high-volume range days, the tight tolerances in these dies help ensure your reloaded rounds perform without hiccups in your AR.
The set includes a Small Base Sizer Die engineered specifically for AR-style firearms. The reduced diameter of the small base die sizes your cases to tighter tolerances than standard dies, which is critical for semi-automatic bolt cycling. Paired with a Taper Crimp Seater Die, you get the two essential dies needed to complete the reloading process—resizing fired cases and seating bullets with a consistent crimp suitable for semi-automatic feeding and extraction.
If you're reloading for a 6.5 Creedmoor AR or similar platform and want dies engineered for reliable chambering and performance, this set removes guesswork from the equation. RCBS builds its dies for shooters who expect their equipment to hold up under real-world use.

Frequently Asked Questions
Will this die set work with my AR-platform 6.5 Creedmoor rifle?
Yes. This set is specifically designed for AR-style semi-automatic rifles chambered in 6.5 Creedmoor. The small base sizer die is engineered to size cases to the tight tolerances required for reliable feeding and extraction in semi-automatic actions.
What dies are included in this set?
The set includes a Small Base Sizer Die and a Taper Crimp Seater Die—the two essential dies needed to resize fired cases and seat bullets with proper crimp for semi-automatic rifles.
Why use a small base die instead of a standard die?
Small base dies size cases to a reduced diameter, which ensures tight, consistent dimensions necessary for reliable chambering and consistent bolt cycling in semi-automatic platforms. This is especially important in AR rifles where loose tolerances can cause feeding or extraction problems.
Can I use this set with a single-stage or progressive press?
These dies are compatible with any standard reloading press that accepts standard die threads. Confirm your press accepts standard RCBS dies before ordering.
