Description Ruger front sight screw ALLEN HEAD *6-40* for PRE-OCT-2019 Ruger Mark 1 2 3 4 IV & All 22/45 (Except LITE) Pistols 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 These use 5/64″ Allen Driver. 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
