I have a NIB Lyman MJT 20 globe front sights with changeable inserts I would part with.
Think the sight height there is 0.70"
I would probably need a 17AHB, with the 0.40"
The top of the notch on the low leaf is about 0.36", which is almost too low for globes, unless I build a platform for the rear - or take a few hundredths off the bottom of the AHB.
