Upon publication of the rule, and until further guidance from NJSP and the ATF, RTSP will no longer sell or ship pistols/Other Firearms with stabilizing braces. We want to assure you that we remain committed to supporting the rights of lawful gun owners while this issue is being resolved through the legal system. Stay tuned for updates as they become available.
