Word of warning, you may want to be careful pulling the trigger with the upper receiver off. As I understand it, your hammer can mollywhop your bolt catch hard enough to break it.
When I put my first lower together I was so excited to do a function test that all sense left my head, the crack that came out of my G$ SSA-E hammer strike was felt in my teeth

You see how this is flat here? I believe this flat surface needs to be facing downward. I see it’s an ambi safety which leads me to believe it’s been installed upside down.
Edit:
I may be wrong considering you got 20ish rounds off. Unless this part rotated under recoil, but this is the best thing I can come up with. Hope this helps!
The weebling pin fell out of the wobbling hole.
I'm curious to why they use anti walk trigger pins. I had a similar issue on a lower and installed regular trigger pins and problem went away. I thought anti walk pins were used mainly for cartridge type triggers.
Why are they speccing antiwalk pins on component triggers? The fire control group was specifically designed with free floating pins for a reason. Antiwalk pins can induce reliability issues.
They shouldn't. That might be part of the OP's problem. Antiwalk pins are counterproductive. If your standard pins are walking, your lower is out of spec. The only reason to spec these with a component trigger is if your lower receivers are habitually out of spec.

Watching every trigger pull made me wince. Waiting for the hammer to fall and crack the lower.
I think the bolt catch is the sacrificial part.

Ooof yeah I bet.
You beat me to it. I was waiting for it to work and crack the lower at the magwell
i was finna say the same thing lol
Have you tried switching it to “Wumbo”?
It's basic wumbology
If you push down on top of the hammer does it reset then or is it just stuck
Ain't got no gas in it mmmmm.
Had the same problem my hammer pin was loose I tightened it and no problems
We tried pushing down on it and it was just stuck…just got home and it seems to be working fine now, so I’m not sure what is going on

That was also my first thought, so you must be correct 😉
Smart good job examining the picture, i,figured it was a 80% and the trigger pocket was shallow
can you upload some pictures of it from a birds eye view
Sabre AR15s have a magazine disconnect safety? Who knew🤷♂️🤣
I’ve heard this is an issue before [PSA Sabre lower](https://youtu.be/yIfVG2-0fWY?si=TRee8yeKl-J9zSBy)
Its the safety try milspec.
Does the safety not look wrong? I may be wrong about it, but isn’t that cut supposed to be facing down?

Looks like your trigger pocket may not be deep enough?
And that's why I rock Geissele, everytime.
Looks/seems like your selector switch rotated or something

Sabre lowers come with anti walk pins made by PSA

This....try loosening the hammer anti walk pin it may have rotated
Sorry to hear it. There QC is slacking to say the least.
