Burris uses a different laser to etch the glass than most manufacturers.
I know very little about lasers, but I know I saw it when I toured the facility last summer. And was told it was state of the art, purchased specifically to cut the SCR2 glass in Greeley. A high magnification zoom shows crazy good corner detail on all the cuts of the reticle versus a lot of rounded corners and edge fuzziness versus other reticles. I don't know if that impacts the appearance to the naked eye, but the reticle is definitely a finer cut.
