So what about all those AR15s listed for sale that are really PA15s or CM15s, FN15 etc. Even Armalite, who the name AR was coined for/by lists their rifles as M15s. Last I checked it could not legally or technically be an AR15 unless it was made by Colt since they bought the rights and the name from Armalite. I see guns listed all the time as an AR15 when it would actually be listed on a 4473 as something else. Same with AR10. PSA never made an AR15 or AR10 but you see them listed every day. What's the difference? If I have a rifle and on the side it says "M16A4" then it is by law an M16A4 regardless of the FCG. That is much more accurate than all these non AR15s that get listed as AR15s and yet everyone excepts it without question. This is really a non issue as far as I can see.
This. Exactly.
