Henry Repeating Arms manufactures a number of repeating rifles, mostly lever- or bolt-action, for sporting, hunting and other recreational purposes. Henry rifles have a reputation for being solid, reliable firearms. The sights used on modern Henry rifles are all traditional dovetail sights, meaning they are relatively simple to remove in order to add replacement sights. The technique used for removing or replacing dovetail sights will be the same regardless of the caliber or type of firearm.
Items you will need
Metal punch
Brass hammer
Replacement sights
Gun lubricant
Large towel
Point the gun in a safe direction and open the chamber. Visually check to make sure that the gun is unloaded before proceeding. A "safe direction" is any direction that will not hurt people, pets or damage valuable personal property if the gun were fired.
Spread the towel out on a flat, solid surface and lay the rifle down on top of the towel.
Remove the front and rear sights by tapping them firmly from the side with the punch and brass hammer. Continue tapping until they are both removed from their respective slots atop the barrel (the "dovetails"). You may need to spray some of the lubricant onto each sight to make them easier to remove.
Align the bases of the replacement sights with the dovetail slots on the barrel.
Tap firmly on the replacement sights until they are aligned correctly with the rifle barrel.
