I am wondering where the design for modern military front sights came from and why. I am talking about the post sight with the curved "ears" on either side. I know that the ears are supposed to prevent the post from being damaged or bumped out of alignment. Was the curve of the ears supposed to provide some benefit? I shoot Highpower rifle so I spend a lot of time looking at that crazy thing.

This same arrangement was used on the M14 and M1, I believe. Not sure about the Springfield or Krag. Did they have receiver peep sights, or an open sight in front of the chamber?

I figger the curve was so the wing stayed away from the sight. If the wing came straight up from the base, it'd be pretty close to the blade.

I've seen protective ears on flintlock rifles in museums.

I think the first wide-spread use was in the 1890's on early bolt rifles used by cavalry troops.
The protective ears prevented the leather scabbard from catching on the front sight, or from wearing the finish off too fast.

The curved sides prevented the ears from being confused with the actual sight blade.

The "ears" also help you quickly aquire your target, this of it like a funnel to guide your eyes right to the post.

I thought the curve was to allow a better field of view, while still allowing

max. protection.
