Yeah, I'd seen them while shopping for options. Interesting that you say they're better than Dawsons, so I'll go with your suggestion if I can't salvage the Trijicon rear. Definitely a wider front than what I've got right now though.
Co-worker took a look at it and is willing to drill through and tap for a larger size with 5/64 drive, but first he's going to let it soak in some solvent that works against Loctite to see if we can save ourselves some effort.
