The Lee 223/AR/5.56x45mm NATO Remington Micrometer Full Length 2-Die Set includes Full Length Sizing Die Micrometer Bullet Seating Die Universal Shell Holder Powder Dipper and instructions with load data. Select this die set if you are reloading new or mixed range brass.

If you will be reloading for hunting or your firearm magazine limits the overall length and prevents your bullet from touching the rifling we recommend restoring accuracy with the accessory Lee Factory Crimp Die.

After full length sizing and firing you now have brass that is fire formed to your chamber. Consider our neck sizing die for longest case life and best accuracy. Sizes just the neck and requires no case lubrication.

This die set may be used to load 5.56 NATO (5.56 x 45mm) brass. You must follow load data published for the 5.56 NATO available from your favorite powder manufacturer.
