Sighting Problems on a late Inland

[USGI]

There it is. I can't believe the discussion continues as if the question were not answered.

The actual question was not how to sight in a carbine, but how this carbine escaped getting sighted in. The sight doesn't appear to be a recent addition. I'll check the blade height, but it does appear to be close to "new" dimensions. It's not exactly what I would call a new sight, though! - Bob
