This is the Upgraded Action screw set.
This is a hardened action screw kit for a CZ 457. This should fit all variants with the factory bottom metal.
These will last longer and look sharper on your build. These wont get disfigured and twisted like the factory torx bolts will when doing barrel changes.
This a DIY kit. fit and finish will need to be done during installation.
They are left long and require fitting. hese are DIY so fitting of the screw head may be needed to obtain a flush fit in the bottom metal.
I also have Upgraded Stainless Steel Drop in Action Screws and Replacement Barrel Screws for the CZ 455, and Cz 457 as well as pillar kits for this and other actions.
