From the Knights and Hodge are imaginary modcast the crew had good things to say bout them Have heard generally good things as well. Not used one personally though so take that for what it is worth. Maybe I need to break down and grab one to replace a trigger in another rig I have.
I got one shortly after they were released. It felt pretty similar to my SD-C's but with a slightly crisper break (didn't own an -E for comparison). I preferred the flat face and break of the SD-C and ended up selling the MBT-2S for what I paid. It was nice, though, and if I didn't have 1:1 SD-C's to rifles I would have kept and used it without complaint.
I have two and like them, but the first one I had from three or so years ago, probably their first sale on them, went TU after about 1k rounds. It lost pull weight until it was just over 2 lbs, and if I was applying pressure to the trigger, but decided to let off without firing, the gun would fire.
I haven’t had either of those issues with the newer two, one of which was the replacement that Larue sent for the first one, but they don’t have as many rounds yet. One of them is starting to get close though.
If you pay attention to it, for $100 they’re hard to beat.
