What do you wanna bet the reason for the mfr disclaimer is because some "concerned citizen" filed a complaint with the AG for Michigan state because some kid got caught shooting his "Air pistol with shoulder stock" at something he shouldn't have, or some such, and the AG contacted the mfr and threatened them.

I bet if nothing else changed in ten years or less that disclaimer would go away.
