Gotta love a confusing conversation
OP, a picture is worth a thousand words.
As we've already determined, you meant to say blade sight, not post. I think.
And everyone knows the ramp part of a sight is the part that goes from the barrel upwards to the apex.
That ramp is typically serrated on a modern sight. But on a ML it was pointed forward towards the muzzle so as not to pick up glare. Although if memory serves me Alvin York applied a little spit to cut down the glare. Whether shooting turkeys with a ML or Nazis with his movie 1893 Springfield. Which does have a blade style front sight.
But Hawkens have a stock front sight like sketched above by 64Springers young child
And IMO that's really not what you are describing either. But it might be. And the stock sights were made of steel in production guns like TC.
But if you have the gun I just sold I had it replaced with a rounded blade because my eyes like it.
Who made your Hawken?
And how about a pic of your sight. Or at least share your thoughts so we might know what you are referring to.
