I need to see some pictures of this. Please keep us up to date as to how they handle it. Custome service is a BIG deal to me. __________________

I have called Bushmaster about the gun. The good news is I was told that it would be repaired under warranty. The bad news, it may be 1-2 months as they are in the process of moving some of their operations. Bushmaster is paying the Fed Ex charges for shipping, so there is no cost for me.
The first two pictires show the crack in the receiver, and the last pictures show some of the brass. The top row is the split cases, the bottom row is "just" bulging cases. The Bushmaster service rep didn't think the split cases and split receiver were related. I can't swallow that. The cases didn't use to split after firing. Now the receiver is split and the cases are splitting. Looks like a duck, walks like a duck, sounds like a duck,,,,,,,,, well, you get the idea.

After looking at the pictures I have a theory. The buffer is not touching the back of the bolt, so there is no resistence to the rearward movement of the shell/bolt after firing. The recoil spring holds the bolt closed for a nano secound when the pressure is high, but without that spring pushing forward the shell can start moving rearward while the pressure is high. With that rearward movement the casing becomes unsupported and the case ruptures.
Just a theory, but I'll put a dollar on that theory. __________________

Well, first off, super kudos to Bushmaster for offering full warranty service, even if it will be slightly delayed due to technical circumstances. Just the fact that they'll accept responsibility for a defect and not put it off on you is very heartening. | |

I shipped my rifle back on 4/28/2010. Still no word on when my rifle will be ready  . __________________

Is there a captured nut or threaded insert for the pistol grip bolt? I was wondering if over tightening the bolt may have compromised the integrity of the receiver in the area of the split? Let us know if you ever find out what the cause was.
I'd bet on your theory as to the ruptured cases as well. __________________

Most likely not. Overtightening of the pistol grip bolt will split/damage the pistol grip long before it will damage the aluminum of the receiver. | |

Not an aluminum reciever __________________
I could make a list of a bunch of guns i have, or "have", or wish I had. Why would one feel compelled to provide that infornation freely? Do you feel the need to show off? Is it some immature game of oneupsmanship?
Why do you feel it necessary to list your guns? | |

Then yup, that would do it for sure. In fact, looking at the damage itself, that looks like exactly what happened. | |
