Not to fuel the fire over Hesse/Vulcan, but the attached pics are of a Hesse AR reciever that belongs to a friend of mine. He finished the build, and had to travel, so he allowed me to do the test shooting. This reciever failed after the second round I fired. Not the second magazine or case, the second ROUND. The build was done with all new lower parts and an existing upper. There were no goofey components or junk involved. The owner has about 5 other AR's, and experienced in building, since he has built them all.
Hesse required the whole rifle be returned to them before they would comment on making a warranty adjustment. The owner refuesd to send the whole rifle, since only the reciever was bought from Hesse (through Fulton Armory, I think). This was about 3 or 4 years ago, but the reciever resides in Dallas, Texas, and would be available for anyone that wants to examine it. Bottom line, no warranty at all!
Here is what happened at the range:
Specifically, when I shot the rifle at Gibson's Outpost (SE Dallas), I loaded only 3 rounds in the magazine. I did this to make sure that if something went crazy with the FC group, the rifle would not go full auto on a full mag. First round was fine, but felt funny, like the rifle was tight. The second round fired fine and the action cycled, and then I found the rear sight against my glasses, and something falling into my lap. I first thought the stock came off, but realised after seeing the back side of the lower still attached to the stock. I looked up at the back of the upper with the bolt carrier in front of my nose, a locked bolt on a live round, and my finger off the trigger (fortunately).
I hit the safety, and pulled the bolt charging handle, which ejected the shell, and pulled the bolt carrier and handle all the way out. I re-cased the "rifle" and took it back to it's owner when he got back in town.
Anyway, you descide. Maybe Vulcan has done better, but the origional Hesse company doesn't hold as one of my preferred manufacturers.
