Stupidity broke my upper. Can this be fixed? Worth fixing? Worth anything the way it is?
Can not be fixed.
7075 is non-weldable.
If you have a desk and some papers on it, you should be fine. Condolences.
Mind if I ask how??
I was swapping upper receivers “quick.” Realized I didn’t take the A2 off and with the upper in the vise blocks with the barrel still in it decided I would put a wrench on the A2 and…
Ewww sorry guy, live and learn.
Sorry but it is toast, or as another said would be a good paper weight.:rolleyes:
I figured as much. At least it wasn’t the MUR upper I was swapping it with.
I’ve done dozens of these, just wasn’t paying attention. Guess I’ll leave it on the bench to look and remember to slow down next time.
Complacency in the shop has ruined more sh!t than inexperience IMO. When you know that your out of your element, your very careful. When you think ya know, ya make mistakes. Speaking from more personal experiences than I care to admit…
At least I’m not alone. 
Off to the Where Can I Get It thread for a new upper…
That’s a bummer and bad timing too. BCM just had blem uppers in stock last week.

I’m confused…isn’t this how you change a fh? I saw Barry Dueck do it.

Ouch, that makes for a couple of choice 4 letter words.
I’m guilty of it myself. I was building a bunch of rifles last week and forgot to install a gas tube on one of them. While it did not damage the rifle, it made a damn fine bolt action AR.
I see a 22LR upper in your future.
Still not sure why the upper broke.
I think he had already loosened the barrel nut and then went to loosen the flash hider.
Yea. Get happy and in a hurry. I bent a gas tube that way(barrel nut does have to come off before gas tube right?!)
Slow down and think. Learn from this.
Had he not, life would be good, yes? Sorry, not mmqb ing, just learning.
Damn sorry that happened.
I am also confused on how that happened. Though I know its not the right way, using the upper receiver action block I took off A2’s and installed new comps, and the upper did not even really flex at all, not close to break.
How is that wrong, both Brownells and Surefire have official videos showing this as the correct method. Upper with a block in it, wrench to the muzzle device.
