Are PSA still trying to figure out what's wrong with their

Why 9mm rifle?
Why not thompson?
Why don't they make .50ae rifle more common?
Where am I, what's going on?
Who are you, this isn't aol!

Not thompson because it was a good 45 SMG back in WW2. But nowadays you can get much better ones. Also he's buying an upper, hence he can decide to swap to non-pistol ammo if he has the money to.
50 AE wouldn't be a good rifle or SMG cartridge. Too difficult to handle on an SMG and too unpredictable on a rifle. 500 S&W might work better (some /k/ommando actually turned his mosin into a 500 S&W gun)
You are on 4chan. We're talking about 9mm uppers.

You're always going to get troll answers on this board.
Get good at telling the difference between fake ones and real ones and you'll be fine. Never give up hope.
