If the front you're using already works, the NECG should adjust to work just fine. Still, with aging eye which don't define the bead as I'd like, I replaced the Ruger bead with a NECG blade- they (NECG) makes several front sight options for Ruger ramps.
One thing to be aware of, if you try to use too large an aperture on the NECG, you may run into an aperture with flat sides. The NECG sight window is not large enough to accomodate the full view of the larger apertures. (I'm referring to Williams apertures, not the ones that come with the NECG sight.)
