Just in case anyone is wondering Marblearms got back to me and said this “Our ramps have a .010” bigger dovetail then Lyman’s dovetail. So, the Globe will not fit our front ramp. It will slide thru the ramp.”
so going to try a Williams ramp.
Sorry to revive an old thread. Just piecing together my new Ultralite and purchased these parts.
Marble Arms Front Ramp (Mfr Part: 072310)
Lyman Front Sight (Mfr Part: 3171076)
but the Lyman front sight dovetail is flopping around in the marble ramp. Did you shim it?
