D-Series Hard-Coat 7075-T6 Aluminum Button

$17.99 $18.90

available as an UPGRADE KIT

This can be used to UPGRADE or replace a D-Series Button, notably converting a Red Button to have a stronger button made a select color choice.

*It is not recommended to change an SS button to a Black Hardcoat aluminum button on a Full Hardened SS version as this would be a downgrade in strength with a heavy handle resulting in a low lifetime of the button due to impacts.

Compatible with:

UPK-D1, D2, and D4
