What Am I Missing?

[SAnd]

Ok lets say someone has a complete AR with a 20 inch barrel upper with a A2 receiver and front sights. He finds a good deal on upper with a 16 inch barrel with a flat top receiver and no front sight, which is what he really wanted anyway. He gets it cheaper without the bolt/bolt carrier assembly which he already has.

So now he just wants to get rid of an upper he never really liked anyhow.

Yeah, I get that. But there hasn't been a complete upper (that I've seen anyway) in the TP for a long time. It's not just the occasional upper that might fit into your scenario...it's every upper listed.

I'm guessing it's just the $$.

I'm guilt of this. Did it a couple years ago. Same reason, bought an upper with no BCG. It was cheap. I sold the unused upper cheap. I should have sold it with the bolt, not everyone has the gauges to check head space.

I doubt headspacing would be an issue with quality US-made parts. Probably no need to worry about that.

I would worry about someone using cheap/imported parts from suspect sources just to make a quick $$. Too many AR-15 "armorers" out there these days.
