Armorer’s Block for the SIG Sauer® P320. Designed by the team at Grayguns to assist qualified armorers when upgrading components, adding spring kits and completing work on the fire control unit (FCU), striker assembly and slide.
Facilitates disassembly and assembly of the P320’s FCU. Two-sided to allow for removal and installation of one-way pins in the FCU.
Note – If you have a P320 with a manual safety, those parts are removed first, prior to placing the FCU into the armorer’s bloc
