Description

Fits ALL Ruger Adjustable Sight Mark Series Pistols (see notes below)
Ruger “LITE” is still a Mark series pistol

Ruger Mark IV pistols from late 2018 on have a NEW rear sight
This part is NOT compatible with the new design sight (see pictures above)

This spring is also used on most Ruger Adjustable Sight Revolvers they may need 2 springs though

This should fit Pac-Lite rear sight also

Very early pistols used a “Micro” brand rear sight,, this blade should work but will need fitting

If your pistol has a NON-Adjustable rear sight, you will most likely need a taller front sight if installing this adjustable rear sight.
