So how is a Lyman 57 or Redfield 70 or Lyman 30 1/2 without a screw in aperture any different from an M1 Garand or M1 carbine sight?
I've shot them all extensively. I can clearly see the outline of the back sight hole on all of them. None of them qualifies as a ghost ring sight by my definition.
You look through the hole and your eye instinctively centers the front sight.
The size of the hole may be different, I but see absolutely no difference in the method or results.
I think we are splitting hairs on the language.
Aperature size makes a huge difference in my shooting. Too big and I generally can't hit a barn from the inside, too small and it's hard to see anything unless it's a sunny day.
