Memorial Day Sale! Use Code USA50 for 50% off 223 & 30cal Flare Expander Dies with purchase of any Rifle Sizing Die!


Mighty Armory offers three series of precision CNC machined decapping dies depending on your brass processing, loading and press. 

Mighty Armory’s innovative decapping die designs utilize a spring-loaded primer flicker. The spring design allows upward shaft movement before contacting a stop. The rebound of the spring forces the shaft down and flicks the primer off the pin, shooting it through the press funnel and eliminating primer pullback.  

Our designs are crafted to be tool-free, trouble-free, and ULTRA TOUGH! Best decapping dies in the industry, hands down!
