I totally hear ya on that. was merely brainstorming on what could cause the brass to implode like that as it looks sucked in vs formed in by a piece of debris. Also when I looked carefully at the very first pic that was posted, even the leading edge of what was left of the neck has an inward burr or rolled inward edge..... very confusing LOL
Generally , the pressure of normal operation expands the brass into the chamber..... doesn't implode it
Did we ever get an answer as to if there is still a case neck stuck in the chamber?
If it did break off that would allow the gasses to get in around the remainder of the brass and crush it in. Just brainstorming as well, I've never seen anything like that before.
That primer looks like it was nearly punctured as well, might be a little too hot for this rifle.
What powder were you using? Even a mid book load can be too hot for some rifles like this, maybe the chamber was a little tight "match chamber", combined with maybe a less than ideal powder choice, maybe also combined with a little too long of brass, the tolerance stacking may have led to your kaboom.
My Modern Hunter (6.5CM) hates Hornady Superformance, will pierce primers, jams all the time, and groups like a shotgun, I handload using the same projectiles and it cycles perfectly and groups really nicely. Just an example of how finicky a semi auto can be when factory loads are too hot for a gun, same for reloading, a mid book load may still be too hot.
Also, stop loading lead tip bullets in your rifle, it's probably got nothing to do with what happened but semi auto's don't feed them well and the tip will get mushed a little as it goes in which will decrease accuracy.
BCL might be very interested in studying your rifle.
No doubt they have tested specimens to destruction, but having a look at yours should be of value to them.
By all means get in touch with them. They might replace the rifle, simply on the basis of good customer relations.
I would suggest that falsifying a warranty claim, lying about the use of handloaded ammunition might be unwise.
Maybe just don't volunteer the ammo info unless asked specifically about it.
I agree with Wall-mart greeter, I don't get the feeling they do any R&D at BCL, They've had way too many issues to believe they have any idea what they're doing there. That first batch of 77 gen 1 rifles must have had at least twenty with problems, in some of the pictures posted the issues were so obvious they should have never made it out of the shop.
When guys are buying a complete rifle and then stripping it down to the receiver and throwing out all the stock parts to build a new rifle just because it was the only affordable AR-10ish rifle on the market it should send a message to people with less experience that this is not a good product.
I doubt very much BCL does any testing... otherwise those beveled ejectors wouldn’t have made it out the door.
BCL has their customers pay full price to do the testing for them lol
The beveled ejector is more aerodynamic, it's just one of BCL's "improvements"
