What ever you do not send them back all the ammo. Ever issue I have ever seen that was the first thing they ask for. Once they have your ammo you have zero proof of anything. They can say whatever they want. First do a basic check of the ammo. Even then hold on to a bit.
Measure COAL and weigh the ammo. If it's overcharged or some are loaded long that's easy to catch. Look at the other fired cases if any for clear over pressure signs. Check for 300BO rounds
As its a homebuilt gun unless you can prove the ammo is loaded hot (double load etc) I doubt you will see a dime from them beyond free ammo replacement. Way to many variables there of how it can happen thats notbtheir ammos fault. You likely purchased the BCG and barrel separately so no proof it was properly headspaced. That kind of stuff would have to be inspected and verified from certified source. Cost you more than the whole gun.
The only time I have seen a manf cover a blowup was on a Stag 6.8 SPC which had a defective barrel or barrel extension back in `09-10 and over pressure ammo. Both worked it out qnd a new gun was shipped.
I have seen a couple dealing with the SW MP9 when it had early unlocking and fired out of battery that got replaced but by the gun manf.
I think I only know of one time outside the Stag above where an ammo company paid anything toward a firearm replacement and they again worked it out with the firearm manf to send them another one. It was an AR15 but can not recall the brand. But again these were factory guns.
I have never known or heard of an ammo manf covering a homebuilt AR or any self built firearm where it was damaged.
The question becomes was it a single cartridge over charge loaded long etc or was it an issue with more than one? If it was a one off your SOL.
That damage looks to be what I would expect from a 80-85k psi load in an in-spec good condition AR15 specifically the bolt and extension.
Weighing should hopefully catch if any of the rounds are over charged.
Did you only fire one round from this ammo lot or was it out of multiple rounds. The others firing and ejecting as you would expect and then boom?
Without clear proof it was their ammo at fault, from their point of view you could have easily fired a squid with now a bullet in the barrel recharged and blew your gun up. I have seen this numerous times, so it's understandable. Not just that they from a liability standpoint never want to admit fault. But so many people that do bonehead things try to get manf to cover their idiocy. Same thing you see with warranties. When it's a actual legitmated claim without clear proof it's treated with extreme suspicion. For all they know you could have blown your gun up with bad reloads and are trying to get them to foot the bill. It's why this kind of situation sucks for the gun owner that really had a legitimate issue.
What the ammo and firearm companies really fear is physical injury. It's usually to hands and face regions. Just a single minor ER visit will tend to be worth a few ARs in cost. It's a PR nightmare.
If you find rounds that are over weight say by a few grains make sure you keep a couple. If you do find others and have enough of them you could pull one bullet and weigh the charge. Then pull a normal weight one and do the same. Be a good idea to have the camera running and be sure everything stays in frame.
But without finding rounds that are clearly overcharged I do not think your odds are good. But who knows??

. But thanks for actually addressing the question.
