need help with AR barrel
So heres the story:
I bought a stripped AR barrel a while ago from an older gentleman that said it was for an AR 15. It looked like an 18" version of a 20" pencil barrel. I was trying to make a straight pull AR upper. So I asked around and found someone to plug the gas port and install a barrel extension. When he got the barrel, he said it was not an AR barrel, but possibly a Daewoo 200 barrel. So I figured it wouldn't work , but he managed to get the barrel extension on, and headspaced, and sent it back to me. So I figured it was good to go, and installed it onto my upper, and took it to the range for some test firing to sight the scope. So I ran 10 rounds through it, and the rounds were chambering and firing, but there was a weird kick to the rifle. So I look at the brass on the ground and am pretty shocked to see that the shoulders were all blown out and cracked on the brass. Pics below.
I obviously stopped shooting and went home to try and figure out what happened. It looks like the chamber had two shoulders and the rounds were not seating properly. I sent the pics to the person that installed the extension, and because the chamber appears to be Chrome lined, there is nothing that can be done. I was wondering if anybody has seen something like this before, and what could have caused this to happen. Im kind of bummed that I am $100 into this barrel, and almost had it blow up in my face.
P.S. I guess I still need a barrel to finish this project
