Sig likes to skate on the edge.
They also make an AR "pistol" that comes from the factory with an arm brace that can very conveniently be used as a stock, turning the pistol into a short barrel rifle - another NFA item.

“Skate on the edge”? Are you supposed to be posing on DU?

Sig is merely adhering to the Constitution.

“Sig likes to skate on the edge.”

I think much of it has to do with a cultural set.

Sig is based in Switzerland, which, up until recently, had more firearms freedom than the United States.

I am sure that they clearly see the short barreled rifle and gun muffler laws for the idiocies that they are. Hence, they likely believe that as long as they follow the letter of the law, they should be in compliance.

The idea of a bureaucracy rewriting the regulations to enhance their power is likely culturally abhorrent to them.
