Does anyone know what the difference in height between the "F" marked Colt, and a standard Front sight base would be? Thanks

The bases are exactly the same height overall.  What's higher on the F marked base is the surface milled for the sight blade.  It's .040 shallower than the standard, which puts the standard blade that much higher overall.

Or you could use a standard base with Bushmaster's higher blade.  Works out to be the same.

 BTW: That's exactly what Colt used to do on their carbine types before some "genius" came up w/the F  jobbie
