If you like 'irons', go with the Mil Spec Gas-block front site. If you will want to put some type of glass on later, think of folding.
My old eyes don't do well with irons. The 'co' view thing of using irons while looking threw a low power scope or red dot or the like, drives me nuts (a short trip). It is much simpler to start with flip ups. The change out can be a hassle.
Now you have my opinion. You may now giggle at it and disregard it all.
C'mon Oldpapps, don't be so hard on yourself, you make some very good points! The only thing I'd add is that the front sight post becomes much less of an issue if you can forgo the habit of focusing on your front sight, and just focus on the target and concentrate on putting the dot on target. At this point the FSB should be out of focus and a non issue. Takes a little getting used to, but when you get it, its is insane on how much faster you can be with target acquisition and on transitions.
As for the OP's being color challenged, please correct me if I'm wrong but, you can still see the dot, just not color correct? In which case you may want to look into RDSs with different color reticles. Unfortunately most are very cheap knock offs. Another thing you may want to look into is a RDS with a big reticle, like a Eotech. An Aimpoint 2moa dot maybe hard to find for you. Consider the primary arms m4 clone. It has 4 different reticles I believe tho they are all red.
