I did some searches on Gen 5 sights as I'm struggling a little to find the right front sight height. Using a plain serrated blade with the stock rear, the Ameriglo .200" is hitting a little low. Since this is what they ship with their Gen 5 sets, I was a little puzzled.
Looked all over the rear sight for a "-" or some other marking to indicate if it is 6.1mm, 6.5mm. Nothing.
Oh, wait....
I guess it's "6.1". Duh.
