You might find the ARMs #40L SP an excellant sight.



I Sure Love mine.

As for A2, A3 and A4... A2 is the Military Designation for the fixed Carry Handle model, A3 is a manufacturer (like Bushmaster) designation for a flattop, and A4 is the Military Designation for the the M16 with Flattop, removable front sight, and A knights Full length rail.

Hope that helps.
