Someone school me on AR style rifles.
Why in the EE for black rifles is there posted Uppers and Lowers ? What is the registerable part ?
Is the action on the lower or upper ?
And why in the EE isn't half a gun listed as parts ?
I was interested in gettting into them but it seems complicated

(I haven't done any googl'n yet thought i would just ask)
