Let's try this one more time:For fun let's see if we can match up parts of this definition to the parts of an AR. The more I read it, the less sense it makes that it applies to the upper and lower requiring serialization.
(13) "Receiver" means the part of a rifle, shotgun or projectile weapon other than a
handgun, or a variant of a rifle, shotgun or projectile weapon other than a handgun, that
provides housing or a structure for the primary component designed to block or seal the
breech prior to initiation of the firing sequence, even if pins or other attachments are re-
quired to connect the component to the housing or structure.
At first glance I thought the housing/structure was referring to the upper receiver and the primary component blocking the breech was the BCG. If that was the case this last part wouldn't make much sense:
"even if pins or other attachments are re-
quired to connect the component to the housing or structure."
My interpretation is that the AR15 lower receiver is the housing or structure and the primary component is the upper receiver, which is held on by pins.
This definition has been around for a while and has not often applied to AR upper receivers in the past.
