i want to find a couple WWII receivers so that if i get this problem again, i can have a buck-up ready. if anyone can find a place where they are selling some at a good price i would appreciate it.
It is basically unheard-of to crack a carbine receiver by shooting. The round just doesn't put much of a strain on the receiver. Your receiver was most likely cracked while installing or removing a barrel.
