That certainly puts up a challenge, as I stated above it would be cool if someone made one or the other, FRT is obviously better for the general 2A hobbyist, but even if someone made an SOT version and released the files with warnings of “for SOT’s only.” Perhaps for the FRT version you have a “grip safety” type button that runs the rotating barrels at a fixed speed, and a trigger linked to the bolts so as the bolts move back and forth chambering cartridges it forces the trigger forward and backwards.

I have not printed one, but from what I’ve heard it seems to garner pretty positive feedback. In my opinion, the way to better mitigate the loss of concentricity is to oversize the exit hole slightly larger than you normally would to compensate for this. I don’t believe the all printed system the trident offers is going to be longer lasting than a metal inserted thread adapter, but it does offer a cheaper and easier to make alternative that gives you the QD option. I believe this system would pair great with the aforementioned FTN 4.5 PCC.

Maybe you would consider doing something simpler? Pembie000industries made a trilug can that only requires a cut AR buffer spring and a handful of M3 screws/nuts, (sailing in Odysee under name “Tri-dent”) every other part 3d printed. If you can incorporate that principle, you get the same functionality and QD benefits of a trilug, without requiring someone to buy a brand specific 100 dollar plus part.

Edit: forgot this place Isn’t censored, here is the link to the file, if you want to/ are willing to seriously consider this option: https://odysee.com/@pembie000industries:1/TRI-dent:0
