Not the anon that posted the video link, but my personal experience (And again, this is only me) I have only ever had outstanding experiences with PSA. From Ammo to gun parts. Their AAC ammo always shoots reliably with no jams in my experience (I have gone through probably 10K rounds of AAC 556, and around 3K rounds of AAC 300 BLK).
All my lowers are PSA (Just like most people lmao) because 7075 aluminum is 7075 aluminum. The stamp doesn't matter to me, plus they have those "Gov use only" carbine lowers. My PSA Sabre 18 Mod S upper shoots reliably, accurately, and has had no issues that were not user error. Customer support has always been great as well, but I still like to shit on people for being "poors" as we all do, just as a joke lol.
I like pretty much all brands equally, but PSA holds a special place in my heart due to my first rifle being a rando 16" PSA special back in the day.
Also, I got to shoot my buddy's jakl, and I nearly creamed my pantaloons if I may be honest. I'm gonna get one soon, but an MP5/AP5 is first on my list.
