Suppressor Sunday 1/11/26

Well I said that I wasn't gonna restart Suppressor Sundays, but here we are.

For those who weren't around at the time, I had weekly updates on sundays for my projects. Actually the reason why I started them was to disseminate information about troubleshooting my projects or common questions.

That's actually why I am posting this today. I don't expect this to be a weekly thing, but since release, there have been a lot of questions so I want to answer them publicly as many people may have similar questions.

1. I heard from a few people that they had trouble threading in the inserts. It seems to be a print problem and warping related. I have made a new pack of inserts with slightly looser tolerances. This is available here: https://odysee.com/@Plaboi:2/FTN.5-Looser-Fit-Insert-Pack:8 and also the original release pack has been updated
2. There was a typo in the form 1 tube dimensions for the FTN.5 Rimfire and Tesla coil. The release pack has been updated with correct information. The correct size tube for FTN.5 Rimfire is 35mm/38mm, and for the Tesla Coil it is 37mm/40mm.
3. FTN.5 PCC and PCC flow has a slight change to the filet at the top, near threads, for easier printing. Also there was an error with some flow-through channels not getting gas (thanks SmokeyM)
4. No PET-CF! You guys really like PET-CF. I think it is inferior to PA-CF in the factors that matter for suppressors. Sure, it can work, but PA-CF is much better
5. PPA-CF is weaker than PA-CF. There is a bit of nuance here, and our testing was printed at 300, not 320 so Confuzled has informed me that we are leaving some performance on the table. However, for something like the Shell of the FTN.5 Rifle Flow, I do NOT recommend PPA-CF. I recommend PA6CF because that is what tested better.

PPA-CF is a good option for suppressor body but for the shell, go with PA6CF

6. PA6CF roughly equals PA12CF and PA612CF. I often say PA6CF, but these are all similar enough. PA6GF is also similar but slightly more brittle
7. You guys really like the printed shells. I knew they were gonna be popular, but it seems like everyone is going for the printed shells of the FTN.5 Rifle Flow. That is fine, but remember that the printed shell is the weakest option. Probably wont survive full auto/supersafe. Not rated for 556 with less than 16" barrel. Use PA6CF not PPACF for printed shell. Depending on user feedback, I may release a thicker shell meant to be more durable. Let me know if this is something you guys are interested in

8. Regarding Breek: I will wait to see what their final decision is regarding their Castle Shield and OT line. If they do choose to discontinue it, I do have contingencies. We could make a new "Insert" piece and pivot pretty quickly.

In the past I often had videos, so this weeks video is the top of this page: https://ftn.fun/media

This is an FTN.5 Rimfire Flow printed in PLA torture tested. It shows back to back 160 rounds of supersonic.There are probably plenty of printed 22 suppressors that can handle that round count without blowing up, but actually what is most impressive is that near the end of the video, the shooter can hit a 6" gong at 50 yards still.

It is very difficult to make a PLA suppressor that takes that much heat and yet still not have point of impact shift. There is a significant amount of heat transfer, and a PLA baffle stack can easily be trashed by it.

There is also a FTN.5 PCC video by Prints and the Revolution (form 1) including a night shot. Also tx22 testing by onlyprints

Keep up the good work with the form 1 submissions! It has only been 11 days into the new year, but the number of form 1 applications are incredible. If we keep this up, we can show everyone how much we care about lawful suppressor use.
