AR SERIES SMALL BASE TAPER CRIMP DIE SETS Reviews & Ratings

A must for the progressive reloader. The RCBS AR Series Die Set features a Small Base sizing die and a Taper Crimp seating die. This combination makes reloading easier for AR-style or semi-auto shooters. The Small Base sizer guarantees that the cartridge will rechamber. The Taper Crimp Seater is more forgiving when various case lengths are loaded at the same time. Case neck crimp bulges and buckled shoulders are virtually eliminated when Taper crimping is used with cannelured bullets.

Great as always

Typical RCBS quality. Works perfectly. Interior finish is flawless. Sizes precisely.

A die set for more than AR's

I bought this set because my old RCBS .223 full length die set with its roll crimp feature was causing my cases to bulge at the shoulder and make chambering impossible. And this would happen with even a small degree of crimp into a cannelure after bullet seating. So this Small Base set with it's taper crimp feature solved this problem 100%. Sizing is a bit more effort than my old sizing die, but that's ok with me.

Great AR Die set

Had a small base RCBS die set prior to this set- Seating die on this set does a taper crimp vs a roll crimp. Had used Lee FCD in the past but this new die set works fine for seating & crimping in one shot. Decap & resizing works without issue - Seat & Crimp works great in my progressive press as well. Would be nice to have a fine tuner on the seating die but with minimal fuss I'm within .001 all the time. ~2000 rounds loaded so far and no issues - good product.

Problem Solver

Had chambering issues with two AR's while using another trusted brand of dies. These dies have solved the problem, no more chambering issues in my AR's.
