The RCBS AR Series Taper Crimp Seater Die, .223 Rem/5.56mm (brand part no. 11162) is a single taper crimp seater die from RCBS’s AR Series, built specifically for AR-style .223 Rem/5.56mm cases. It’s made from hardened steel with the same attention to detail RCBS puts into the rest of its die lineup, and it’s more forgiving than a standard seater die when crimping cases that vary slightly in length. The taper crimp applies the proper amount of crimp for cannelured bullets, reducing the bulge and buckling a roll crimp can cause on straight-walled AR cases.

Frequently Asked Questions

Does this die include a sizing die too? No, this listing is the taper crimp seater die only; pair it with your existing AR-cartridge sizing die.

Why a taper crimp instead of a roll crimp on AR cases? AR-style cases headspace off the case mouth, so a taper crimp is the correct choice; a roll crimp can interfere with proper chambering.
