I’ve been digging into this whole binary trigger thing since I moved here a few months back. Honestly, it’s been a bit confusing. From what I’ve gathered, the legality can get tricky depending on where you are in Colorado. Some folks say they’re okay as long as you’re following state and federal laws, but I’m not sure if there are any specific local rules I might be missing. I want to get something set up for my AR but don’t want to run into any issues. If anyone’s done the research or has experience with this, I’d really appreciate any insights! Are there any specific places to check for the most accurate info?
Binary Triggers Legal Or Nah?

You might want to reach out to a local FFL who knows the ins and outs of Colorado's rules. They’re usually pretty good at keeping up with the latest changes and interpretations

You can still own and use one legally today, but you really want to stay on top of what's happening locally. Some cities may already have tighter rules, and the way they enforce them can be all over the place. It's definitely worth checking in on your city’s regulations.

Spent 21 years carrying M4 and M16A2, I can tell you that shooting select fire (3-round burst) is a waste of ammunition in the majority of situations. So while I think binary triggers are legal federally, I don't see a lot of use for one. Of course we know CO State law is a whole other subject.
SB 25-003 signed into law by Polis make them illegal to possess or purchase as of April 10th of this year. So you'll have to wait and see if SB 25-003 holds up in Federal Court, as the CO Supreme Court will not find it unconstitutional. Talk with a lawyer and join shooting rights organizations if you want you're rights restored.
They should be legal and protected under the 2A, and that's my opinion. However, don't get caught with one in Colorado.
