I’ve never seen value as a civilian in burning ammo faster than the 150-200rpm I can do with a SD3G.

The closest illegal thing to this trigger is a bump stock. But there is no stock in this mechanism. It is a kinda internal mechanism, bump trigger.
BAD NEWS
A couple vids show guys running this trigger perfectly, for awhile. Then stoppages occur. They tinker with the buffer, spring, get another upper, etc.
But here a guy took apart one of these triggers and tells us why they all begin to fail. It is one tiny spring getting bent inside the trigger.

Maybe a Mark 2 design will fix this.
The only Rare Breed this guy will own comes from Wild Turkey
Ok, so I had one of these triggers, because I just have to try everything.
In a 14.5 ml Hanson Chf, a5h1/green, lmt ebcg, with xm193, it ran at about 900rpm. Very much like an m16a1. In 90 rounds I experienced no malfunctions. It was extremely difficult to single shot.
Ultimately, I uninstalled it and sold it. I tried getting it running in an MPX and was unsuccessful due to the design of the FRT trip mechanism exerting upward pressure on the MPX trip bar.
Upon exam, I discovered that the trip return spring was kinked and estimated that it needs a torsional spring, rather than a compression spring (especially one at an improper angle). I discovered this on my own, and only found that this was a bigger issue when Rare Breed posted an obstinate message on Instagram regarding people making YouTube videos of the FRT issues, and calling them out as “kitchen table gunsmiths” with an attitude that seemed to claim that their trigger is perfect and doesn’t need any revisions, even though it’s clearly poorly designed in this regard. I looked on YouTube and saw the video referenced here a few posts back. My trigger looked the same, and my findings echo the video OP. The spring design is clearly flawed and either needs a torsional spring or the compression spring on a detent or an all together different orientation.
Additionally, I had a close friend at Sig reach out to the owner of Rare Breed to get him some loaner MPX and MCX for development. I notified RB of the findings re: the MPX and trip spring design, to which I’ve had no response.
The general attitude of RB seems to be passive-aggressive towards the experienced people who have discovered flaws of the FRT design. Rather than take it in the chin, and realize there are some improvements to be made, they prefer to lash out with name calling and shit posting. I sold my FRT, ended the experiment, and won’t be buying another. I would expect no warranty support in the extremely likely case that the trigger malf’s.
I think the design has merit, and I honestly believe that the concept could easily be designed into a product that actually works well and fixes the shortcomings of the FRT while not infringing any alleged patents. I liken the design to a reciprocating charging handle, as trigger pressure creates feedback on the hammer. I think there should be a way to create a leverage system which resets the trigger without allowing the trigger to create a feedback loop. And don’t even get me started on the trip spring, that thing doesn’t look to have gotten more than 10 minutes of attention.
I can’t say I am surprised. Before I got this trigger, I estimated RB had a clever design but was not so keen with attention to detail. After seeing Rare Breed blindly recommend an H3 buffer in any gun with the FRT, as well as the red dot optics literally bouncing around in the demo videos, I figured there would be some issue in the FRT that were not QC based, but from a “any engineer worth their salt would have noticed this” lack of attention to detail. RB blindly recommending an H3 tells me that their detailed understanding of the AR15 is somewhat lacking. Almost like they just tried a bunch of different buffers to make it work in their guns, and ended up with H3. Rather than really understanding bolt bounce, but also issues which can arise with over buffered guns (ie: short stroking)
