You also haven't said whether your rifle uses the original open rear barrel sight, or has a peep sight installed - a different height front sight blade would be required for either type rear, the peep needing a higher front than the open would.
According to Numrich Arms, the M94AE Ranger uses an issue front sight blade .575" high up to serial #6,000,000 - over which uses a lower height sight blade, .450".
I would add .100" to those heights, if the rifle has a receiver peep sight. (YMMV)
