I did 600 rounds in one weekend until I ran out of ammo. It’s been good to go since.
Melted a PLA lever, but once I switched to PA6-CF it’s been solid.

You want the “tooth” towards the “T” on the HT logo on the small cam.
If the Detent tracks are on the right, you’d want the tooth forward from the observer.

Happy Thanksgiving to you and yours!
Stock up for your next build with our Kabuto 3-position FRTs, or get squad ready with our 10-pack Super Safety Bundle.
On a personal note, I appreciate you guys being so resilient this year. The Reddit meltdown was rough. But here we are. Still going strong. Hope to see some awesome builds in the new year!
Can't stop the signal!

Hey everyone! Wanted to share what we have available for those looking to upgrade their builds with an FRT or two.
We cater to a wide market, so for a lot of you 3D2A folks our DIY options probably would ring home the most. Granted we do have more drop-in/assembled kits at a higher price point.
I host FOSSCAD.io from FRT sales mostly. Some folks have asked about donations, but I don't feel comfortable talking folk's money without giving something in return.
So if you're in a legal state (see !supersafety@fosscad.io for the legality map) - and wanna support - buy an FRT today :)

[BETA] ROF Bot Testing
(thelemmy.club)
As some of y'all may have noticed - there is a new @ROFBot@fosscad.io - I'm developing it myself.
Will eventually open source. But it's a bit of a buggy mess right now.
Please be patient with the bot, and take results with a grain of salt for now.
Attached is an image you would get commented on your post.
I'm playing around with the backend to use different strategies.
There is this GUI that u/schlarpc made: https://schlarpc.github.io/rof-gui/
It uses similar envelope detection, but a manual fixed threshold. It also reports the whole RPM of the clip along with mean/median burst rates. The downside to this is it caps out at a minimum spacing of 50ms per shot (~1200 RPM)
We're taking a different approach, attempting to comb through peaks and find shot audio, while filtering out echos/ejection noise.
It's buggy. But i've seen median error rates as low as 2% over my test data, but when it fails it fails hard.
Long story short, bot reply might be full of crap, but all the data gathering helps!

Map of FRT Legality State by State
(thelemmy.club)
As of Oct 27th, 2025.
Alaska is green, Hawaii is red. Colorado is only banned in specific counties. But I only had polygon data for the whole state.
Yellow means there is either a Bump Stock Ban, or other “Trigger Activator” Ban that specifically mentions “recoil” as the mode over operation.
The litmus test for legality there is whether or not arresting the recoil (bolting rifle to table, etc) would disable the functionality (i.e.) like a bump stock.
I’m by no means an authority on this, but from my research this is what I got.
Feel free to comment/challenge any states, and I'll update this post.
