Filling unused scope mount holes in receiver

[major519]

Looking for guidance regarding unused tapped holes in a firearm receiver.
I previously asked the question in Optics regarding screw sizes so I am that far.
Is it usual to fill unused holes in a receiver (for both aesthetics and protect from dirt / water)?
If one were to use something like a set screw, any worry that it will
imbed itself deeper and perhaps cause function issues or back out? Semi permanent Loctite?
Appreciate the tips

Use plug screws, the kind with a head. Should be readily available from gun part dealers.

I use wax
wax colored close to what the ambient looks like if possible

The headed set screws usually protrude and grab cloth when wiping... I prefer short headless set screws with a daub of blue Loctite. Easy to remove later but they stay set...

If they are 6-48 look in the EE under Other Stuff as a guy has 6-48 Plug Screws listed. It a common gun thread size.

Drop by any gun-store that installs scopes. They probably have hundreds of the factory plugs that they'd give you if you asked nice. One man's garbage and all that.

+1 on this. No need to bubba.
