Go for it! Irons are fun.
When I shot limited, I bought a KNS cross hair front sight, pulled out the cross hair wires, and soldered in a SKINNY single vertical wire.
Up close just looked through the rear+front aperture.
Long distance I used the super skinny front post as normal.
With an A2 rear you can quickly dial if necessary.
Otherwise irons requires a different zero than optics. Usually more like a 300 than 200.
