I’d like to remove the blade in the rear sight for cleaning, but can’t seem to do so.  I’ve loosened the small screw and even removed it, but the blade won’t budge up or down.  Am I doing something wrong?  Or, is this common on sights that have been un-adjusted for a long time?  I applied WD-40 several days ago, which loosened the screw but not the blade.

I’m reluctant to use much force, especially since I have to believe this design was for “range adjustments”, where special tools beyond a well-fitted screwdriver would not be available.

Thanks for your help,

Dorsey

It’s just “glued” by old oil turned to varnish.  Though I think it’s more trouble than it’s worth, take the sight off & immerse it in toluene (lacquer thinner) which will dissolve the dried oil.  WD-40 is not the best penetrating oil, next time use Kroil.

I’ve never tried to adjust one of mine for that very reason. I didn’t want to ruin a good sight.

Such a fine adjustment on an open hunting sight is senseless, unless you were shooting at precisely known ranges.  Game animals aren’t often that cooperative.  When the shooter is guessing at the range (& not many are good guessers), the steps in the elevator are plenty accurate enough.     

Since it’s not broke, I wouldn’t worry about fixing it.

Instead of wrecking a screw that will be very difficult  to replace, why don’t  you  just use some  Hoppies and a tooth brush?   Can’t  be  that  dirty.
