I am contemplating installing a 14.5" middy on my A1/C7 upper. This is a light weight patrol rifle that will not have any red dots. Will I run into sight/zeroing issues with the "F" sight base in combination with the A1/C7 upper rear sight since the "F" sight base is intended for the standard M4 carbine system setup?
