Hey, my rifle only weighs 12, excuse you

No shit, it's probably a commercial spec upper

Which means, it doesn't have a spec

Milspec aero upper but ok.

Clearly something was off

Why would you need to torch anything though. I'm failing to see this

Theres no reason to torch anything when installing a barrel to an upper

fuck it man

You know what

This is apparently normal for this. There are plenty of forum posts about it. And it worked.

@Red Korvo You do you

That's not normal at all

I assure you

@Cataclysmo if I'm a moron for doing this than so is everyone who suggested it.

yes they are retarded

Wait... What's the caliber marking on your barrel @Red Korvo

Post it please

>his parts manufacturers didn’t buy the official specs

It's Aero and Faxon ffs.

That doesnt matter

what was the caliber of the barrel to the upper

5.56 NATO.

If that's for real, then you need to send back either your upper or your barrel

At this point probably both

Out of warranty due to fire damage

"Heavy full auto use - Not Covered"

ATF shows up to this guy's door

You didn't deburr the big burr you set up the first time

And now you're bottomed out on it

It could also be too much grease

Bruh it fit with the big torch I'm gtg.

Can't be, not a blind hole

It's pretty hard to have too much lube, easy to have too much grease

I'm not worried about the excessive heat, you didn't get that thing to 1000F

Did it ruin the heat treat on the upper? Maybe. Will it fail in use? Unlikely

Could still fuck up the heat treat

zenit furniture isnt really super heavy

Galil + LPVO + zenit is fuckin hefty though i'll tell ya hwat

galils are heavy as are lpvos

Milled is just heavy
