ARMANOV Toolhead Free-Float Zero-Play for Dillon XL650 / XL750 Blue

Floating action allows the dies to center themselves exactly over each cartridge for the best possible alignment and more concentric ammunition. Free-float rings are sold separately - QUI
The Zero Play toolhead does not use the original toolhead pins supplied by Dillon. It is bolted with two M3 bolts that lift the toolhead into the uppermost position. When you cycle cases downward, the toolhead does not move, and cases go out in a straight line. Best practice is to loosen M3 bolts slightly before inserting the index shell-plate with case into dies and tightening M3 bolts to the toolhead's best position.
