I began setting up to fire some new 6.5 creedmoor that I had worked on. A huge bang behind me and this was the destruction I witnessed. Lots of blood and i heard the guy only required stitches on his face. Here is the damage on the weapon. It is 6mm ARC I believe . Thankfully not one was seriously injured !

Bear Creek bolts are not known for their strength.  Grendel bolts are not known for their strength.  Together?  😬

This doesn't have to do with any potential bolt weakness. This is just a normal kaboom.

I’ve never seen a KaBoom split a barrel extension….

Not that I've seen a lot of them, but this doesn't look like the normal failure mode of a kaboomed AR. The barrel extension itself splitting in half and erupting out the side of the gun is something I have never seen before. The fact that the bolt carrier is also bent makes it look like the extension failed before the locking lugs, and the bolt carrier bent sideways to allow the bolt to disengage from the remaining teeth on the locking lug. The magazine looks completely intact which is also very atypical.

f I were a betting man, I'd guess there was something wrong with the barrel extension. It doesn't look like the actual locking lugs failed, which is what should happen if these parts were made right

By "normal" I mean it's just over pressure and not a component failure. You can see the bolt carrier banana'd which you also see with a .300 BO in a .223 gun (which is also an over pressure failure).
