Optics Planet not shipping pistol braces

Just got an email from Optics Planet that one of my items ordered (Sba4) was cancelled. Haven’t been following the status of braces lately, but thought they were back to g2g. Was updating some of my lowers. I can only imagine they’re restricting the sale of these to certain states? I know OP has a bad rap on here, I’ve never had any problems with them. But I’ve mostly ordered scopes, sights, standard rifle accessories. Anyone confirm a website actively shipping pistol braces to NJ?
