Thinking about adding iron sights to a few of my rifles, leaning towards the folding multi-leaf express style sights:



Having the fixed blade at the back at 100yrds, then a 200 and 300 leaf would take me outside of how far I can really see.

These sights are available with 1, 2, and 3 leaves (plus the fixed rear blade), any reason to throw a 3 leaf model on?
