[QUOTE="Shadowrider, post: 1595257, member: 3099"] If it was a squib I would think you would be able to tell that there is a bulge somewhere along the length. I'd box it up and send it back. While working in machine shops for over 20 years I bet I only saw a bad heat treat batch twice. Every once in a great while a lot of steel just won't come up to strength at heat treat. You can go back and look at the chemical analysis certs and see that everything is in spec, but the steel just won't do what it's supposed to. It probably had some sort of inclusion or stress riser in the bar stock it was machined from. Neither of these happen very often, but it does happen on occasion. SA will make it right. Edit to add: Looking at it again I see a black "mark" (looks like a letter C) at the muzzle. What is that? Can't tell from the photo but it almost looks like something emedded in the steel. If so that's a blatantly obvious bad piece of steel. Usually you can only see this kind of stuff with dye penetrant or mag particle inspection and I seriously doubt they do that on parts like this, but they probably should. [/QUOTE]
