When looking at my auto ordnance M1 today I saw a cut on the top of the back sight. It is right on top and about 1/16 of an inch deep. What is this used for? Is it for sighting for longer ranges? They must have put it there for a reason because it took extra time to cut it out.
My other question is why there are little dents in a circle around the hole in the back sight. Why were these put there?
These questions are really bugging me so I'd really like some help. Thanks

Pick up a copy of "American Thunder" if you can find one. On page 220 the revised "L" sight is described in detail. If new production holds true to original then the notch at the top edge is for a range of 250 yards and the small aperture sight is for 150 yards. As for the dents, someone of much more knowledge than me will have to help out with that one. Congrats on the purchase, I love my '27.

The "little dents in a circle" are to reduce glare
