>use the cheapest ammo available

You know who you are and you get exactly what you deserve.

>>put $2000+ into a top of the line AR + accessories

That is clearly not a top of the line AR. You can tell just from the cheapo handguard every trash AR uses with that weak ass friction attachment method.

So you did it on purpose?

post blown casing

I hope you kept the ammo box. You'll want to contact Winchester with the lot number, pictures of the blow case, the damage to the rifle, and ask them to replace your upper. They'll want that lot number in case this wasn't a one off over charged cartridge.



This assumes that it wasn't something weird like the gun managing to go off just out of battery however.

Here's whats probably a 300 in a 556. Noveske FA uppers and lowers, happened at a Dead Air event in the middle of a mag dump. There were no 300s at the event, they were thinking a 300 must've ended up in a 556 box somehow

post full autopsy

People talk mad shit about how unfunny and boring Reddit is, but when anons like OP just repost images from Reddit threads, can you really expect 4chan to be any better?

Famous last words

Is Winchester white box actually shit tier ammo for poor people? I bought a box of 200 rounds of M193 a couple weeks ago, have not shot it yet. Is my gun going to explode when I do?

It’s literally Lake City. It is the standard for 5.56. OP is just a dumbass and put the wrong round in the rifle.

There have been hundreds or even thousands of these low effort r*ddit repost threads made over the years. I wonder if it's all one guy. R*ddit seems to produce those kind of people, who post the same thing every day for years like it's their fucking job. It's totally changed the character of 4chan since Digg died and r*ddit got big.

That's at a gun store counter, OP don't own shit and the only thing he's blowing is dick.

I guess he won't make a thread about some retard on fosscad FAing next to his house almost hitting his car and propane tank.

Skill issue

>>57944968 (OP)

Winchester is the current manufacturer at lake city they make ammo for the military and any issue you have is on your end, all the 308 and 223 coming from winchester is straight out of lake city

I have never touched any Winchester ammo after I've had extremely consistent issues with their 9mm and .357 ammo. OP's post just further confirms to never touch that useless trash brand.

>>57944968 (OP)

I had the same thing with similar level of damage happen to me about 2 months ago with Federal American Eagle 223. 



Federal was a huge PITA to deal with. They would not even return my calls until I threatened to get an attorney.



WWB 223/556 seems to have a lot more inconsistences in crimp in the case neck and I've received a couple backwards primers.
