Thread: Bugger - Any bright ideas or she done

Bugger alright.

Unfortunately the harsh reality of the fatigue characteristics of aluminium alloys. They have no limit where a force doesn't fatigue them. They will fatigue and fail over enough cycles no matter the load. Although, I'm sure in most designs and applications they won't be in service long enough to reach that point.
I'm not familiar with this rifle but it looks like the bolt group must of been shock loading the end of the receiver, perhaps the recoil spring had weakened or was too light duty to manage the loading.

I doubt it's fixable without a new receiver.
