It's a Faxon barrel! Pretty impressive if you ask me. I'd love to see a comparison of several different barrel manufacturers after a test like this..

We had another customer email us a link to this right after it was posted.  Impressive to say the least.  

Would be very interesting to see how numerous different barrels would perform under such abuse.  Would be a very hard comparison to conduct accurately due to the odds of something other than the barrel failing first.  But it sure would be fun!
