Elite Iron makes a nice one. Will time up so you can attach without shims and use a thread on can too (which he can also time, here for vertical shift). You can get 'em both with or without wrench flats for easy removal. The ones for smaller calibers, smaller than .50 I mean, look like they'd work quite well.
I went this way in .50BMG myself, on a DTA HTI, but I can't speak as to recoil reduction vs. the DTA brake since I sent the barrel in for work before I fired it (which I still haven't yet!). Anyway, I've heard that the Elite Iron brake is superior to the factory DTA brake, fwiw. But I don't know from experience, I had to change it out if I wanted to switch from brake to can which I intended from the start.
