worn anodizing in pivot pin hole on brand new Daniel Defense upper

[Sry0fcr]

It’s not the swapping uppers I’m worried about. It’s once I get to high round counts. This sucks to even have to worry about with a $1600 rifle.

My wear looks a little different from the OP’s. It looks more like it was from firing as it’s in the direction of the the recoil and is spotty. Will post pics shortly. DD customer service assured me it was normal break in with the steel pins in an aluminum receiver.

Pics?

This is ARFCOM levels of goofball. There is nothing at all wrong with that upper.

Speaking as a quality manager, your statement is not correct.

Thoughts? There’s some crap on one that someone else thought was a crack but it’s just fuzz from cleaning. The only imperfection is the obviously worn spots.

We already established, and you've admitted, that you worry way too much about what happens "at high round count" in other threads... By the time you've worn this rifle out you won't even care anymore. Just go shoot the damn thing.

On average, I separate uppers and lowers once or twice a week if I had to put a number on it.

Why?

And if I'm coming across as snarky, well you've read me right. I'm normally one of the least confrontation members, but this shit is starting to push me over the edge.

Pictures are crap, looks like material has been displaced at the front pin hole?

That's a call they're supposed to make through nonconformance reporting and quality/engineering disposition. If they can't meet the requirements (all of them, material, dimensional & anodizing) through rework, the parts get scrapped, or regraded (blem). They basically shipped non-conforming (blem) receivers and sold them as 1st quality, only question is whether they did it knowingly because someone would have to sign off on the decision to do it under any standard quality system.

It would seem to me that if DD is following their normal process by hand fitting the take down pins, they are following their processes. From what the Sid Sleuths have found on internet searches, it is apparent that this is a 'trademark' (if you would) of Daniel Defense.

This is what the OP said: Funny thing, the upper locks up near perfectly with my lowers. Not too tight, but no wiggle. Think I should contact Daniel Defense about this? Or is this just chipped finish? I don't really care about the latter.

Later post: I talked with DD and they said they do indeed hone pivot pin holes for a good fit.

Seems the process works. Probably meets some ISO 9001 bullshit to boot.

Thanks. I loved that movie.

I stepped away. Went to my property and fired a few Failure to Stop drills with my G19 and went back to working on my roof. All is o.k. in my world.
