TT doesn't list the Diamond w/boltstop on their website. I've bought quite a few of their triggers over the past year, and am very pleased with the ones I have on my rifles. I put primary & special triggers on a couple of custom M700s, and have a couple of Diamonds on Vudoo V-22s. Like 'em all, but especially the Diamonds on the V-22s. You should have no trouble selling the Diamond for what you paid for it, and getting a Special to replace it. Hasn't been that long ago that there was a fairly long waiting list for the Diamonds - bet you won't have any problem selling it.
