Installation

Marlin's

You will need:
Masking tape and a pair of Pliers.

Place a small piece of tape over each of the pliers jaws to avoid scratching or marring the barrel or sight base. Remove the Elevator by raising the rear sight and pulling the elevator toward the muzzle and up from beneath the blade. Now GENTLY* squeeze the arms of the base and remove the Factory Blade.

* The arms don't have to move far to remove the blade, and you can bend them if you squeeze them to hard.

Again gently squeeze the arms and Install the One Hole Blade in place of the factory blade and Replace the elevator.

Ruger's, BFR Revolvers & Handi-Rifles

All you will need is:
1 small Flat Head screwdriver and a Toothpick, Paper Clip, etc...

Begin by backing the windage adjustment screw Almost all the way out.

* DO NOT remove the screw completely at this point or you may lose the tension Spring when the old blade is removed.

With the adjustment screw still in place by a turn or two, grasp the old blade and gently pull upward, moving the blade to align the small extrusion on the blade with the notch in the site body.

* On early Rugers ( pre '73') you may need to remove the extrusion on the blade as there is no notch on the older sight bases. You can easily remove it with a flat file, or flatten it with a Hammer and Punch.

Now that the old blade is out; completely remove the windage screw. (Be careful not to tilt the handgun and drop the tension spring) Using the toothpick or wire, compress the spring and insert the 'One Hole Site'. Be sure that the blade is in the center of the spring.Return the windage adjustment screw and center the blade,

Thats it. you are now ready to sight in your Ruger!
