OR... It is indeed a 12 Gauge Shotgun with a Designation of AA-16 as a Naming Convention...
Which, if you'd read the mention to said gun in another post, breaks from the naming convention used in the real world for
no discernable reason, other than "higher number is better, t'is the future, give it a bigger number", similar to what they have done with the AK series.
Whoever brought it up stated that the AA-12 is named such because it is shorthand for Auto Assault - 12 Gauge (the Auto Assault bit having changed from the original once already). Following that convention, an AA-16 would be an Auto Assault - 16 Gauge.
I don't have a specific reference to the origin of the naming convention for the AA-12, ask the original poster of that point.
MY point is, Shadowrun is vague enough on ammo sizes (beyond weapon class) that you can make up whatever fluff reason for the designation you want. I merely suggested a fluff reason that might appeal to those who have an issue with the "make the number bigger" mentality that
seems to be the SOP for the Shadowrun Devs when it comes to making crap up about guns in the future.

Does anyone actually believe that an AR-180 actually fires 180 Caliber Rounds? Or an M16 for that matter? It is most likely just a designation for the weapon...
And sometimes those designations mean something, the meaning of which varies based on model and manufacturer. Hence this is a spurious argument really. Just because one company uses model names to designate caliber (say, Steyr, with their
M and S series pistols) does not mean this is some sort of industry-wide standard.
Honestly, if you
don't care one way or the other
why they called it the AA-16, why the hell are you even arguing about it? Hell, why am I even arguing about it (other than the fact that I am obviously cranky from lack of food--really need to go eat instead of put up with this nonsense--and the bolded, arrogant "or" you started your post of with just got on my tits)? If your character wants to use the AA-16, buy it, load it up with with Shotgun ammo (whatever fucking gauge that happens to be in Shadowrun), and have a good run.
