MPA FRT Postponed Till Unknown Time

The other day, I conducted my first live-fire test of the MPA Defender FRT I designed. Unfortunately, it seems to have a couple of issues.

1. I've been having consistent OOB detonations (photos shown at end of video). Nothing has been damaged as a result of the 98 rounds I tested with, and none of the casings I looked at had blowouts. However, it's still concerning, and I'm not sure if I could release it like this in good conscience.
2. The FRT wears out way too quickly. The first one lasted about 47 rounds, and the second 51 rounds (in Polymaker PLA pro).

To stop it from wearing out, I've been pondering some ideas for cutting out the part that touches the bolt from a metal blank and screwing it on, and have tinkered with making some printed jigs for cutting said part. I've also considered printing it out of a stronger filament like PA612-CF or PA6-CF, but I'm unsure if these would work well.

To stop the OOB detonations. I have no clue what to do.

Another hurdle is that I have just started another college semester, and things have picked up a lot, so I won't be able to work on it till it's done in about 16 weeks. So I do have to postpone its release to an unknown time, I do apologize.

Stay safe, stay free, Toadlicker556
