The real problem is that the M16/AR15 receiver (the part that the ATF considers the actual “gun”) is a 2 part assembly, top and bottom, and the top part doesn’t have a serial number and can be purchased by anybody because it’s not considered the “gun”.

Of course they don't consider the upper receiver "the gun"; it's just part with the chamber, firing pin and barrel. The untrained, casual civilian firearms owner mistakenly thinks that the muzzle is the dangerous end of such weapons. Fortunately for our society, we have a federal bureaucracy to protect us by regulating and serializing the really dangerous part, the section where you put your finger to pull the trigger. Morons. /sarc

LOL! BTTT!

Luckily, I spent almost ten years in the Marine Corps and learned that the barrel end of the gun thingy is the dangerous end! Best part, it only took me almost ten years! /s

Exactly, and see my previous post.
