Hey mtykim,
If the top of the front sight blade hasn't been filed, those sights will give ya' a 200 yard battle zero. Something to think about as far as shootin' goes. Have a set, will shoot with them when I get a chance. They appeared in the early twenties and were discontinued in '28 or so. What does the rifle look like? Does it have a hatcher hole and scrubbed stock (No markings), serialized bolt? Stippled buttplate? What kind of stock? "C" or maybe grasping groove?
