How do I know if a front grip is legal on my brace-equipped MCK?
Avoid 90-degree vertical foregrips on handguns/braced kits unless you have registered the firearm as an AOW or SBR. If you want extra control, stick to factory-integrated hand stops or angled grips, or consult the manufacturer’s documentation. The MCK does not have a vertical…
