As fire@will mentioned, you likely need a higher front sight. An easy way to figure out which sight height to go with, is to Google: "How to calculate front sight height". This should lead you right into the Brownell's you tube video, that explains the process. Or, go to the Brownell's site and look up: "Sight height calculator". Same info.
While you're there, you can also reference : "M94 front sight blade specs", for even more info. This should give you a good starting point to compare to your current sight. Your choice of sight will also depend on whether your rifle features a ramp, or plain dove-tailed (non-ramped) front sight.
