Description
 
This is the newer Allen Driver type screw (6-40) for Front sights used on Mark Series Bull barrels.
It is slightly longer than the old Flat Blade Screw

In October 2019 Ruger changed front sight screw size in all of the steel Mark Pistol barrels to 6-48.

PAY ATTENTION!!!!!!
Any aftermarket front sight coming with a screw MAY NOT be the right screw for your pistol.


***IF YOU HAVE A "LITE" (ALUMINUM) DO NOT USE THIS SCREW!***
The Ruger LITE currently uses a special longer front sight screw (6-40) because the upper is aluminum and these shorter screws could easily strip the threads out of the upper.

These longer screws are HERE
