Yup.. has to be the fastest OOS on record? Then again this is a "blem" where they don't tell you what is wrong and in general they shouldn't have a huge back-stock of failed process uppers. FYI: I ordered a 300BLK 10'5 upper from PSA a year or so ago.. and the rail slot numbers were hand-written and skewed. They replaced it but that wasn't a "blem". Pffft.

I just received a 10.5" 300 Blackout upper from PSA. It's a snug fit on the 1st lower I snapped it on as a test, and it looks and feels clean. Now, I just need to marry it for real to a pistol lower so I can take it out of the house and test fire it.

I have one of those and I love it. I just wanted to try out a shorter barrel 300AAC model and see the difference. I guess I'll have to wait for re-stock =P
