Hi James, yes, angled grips are generally legal for AR pistols in Wisconsin, as they do not change the firearm's classification like vertical grips might. However, it's always best to verify local laws and regulations to ensure compliance. I would verify with a local FFL.
Stay safe & have a great day!

Just had this very same conversation and my LGS For here in NY! Yes, the angled foregrip would be the "Okay" way to go for you in Wisconsin!!

From what I can see, Wisconsin doesn’t have restrictions against angled foregrips or any other accessories. Federal Laws will also apply. I would def ask your local dealer as well. Visit here: budsgunshop.com/search.php/q/angled+grip

Hi James and welcome to the community. Yes, angled grips are excluded from the "Vertical Grip" restrictions imposed in some states and are 100% legal to install in WI. Cheers, stay safe and enjoy! Some popular vertical grip options are here: budsgunshop.com/search.php/q/angled+grip

There are no Wisconsin-specific restrictions against angled foregrips (or any other accessory for that matter) beyond federal rules. In Madison I have several.
