Long time hand gun shooter, but new to AR style firearms. I have been doing a ton of research and am interested in purchasing a "Other" firearm specifically a Troy A4. I understand what makes a "other" firearm, and why. Excuse my ignorance but by design the Other has a adjustable brace which is not designed to be shouldered. And from what I understand you are not allowed to or only under certain circumstances("sporadic, incidental, or situational")? But every video I have watched of someone firing a "other" firearm has it on their shoulder like any other rifle. I am referencing this blog which was about the only 2020 related article I could find regarding the ATF's stance. But how does that apply in NJ? https://www.80lowerjig.com/blogs/80-lower-blog/can-you-shoulder-an-ar15-pistol-brace-in-2020/ So if I purchase one, and bring it to the range, and I going to be called out for shouldering it? Like I said please dont flame me too much Im new, and just trying to understand this tricky world of NJ gun laws. If this is in the wrong section, I apologize. Please move it, or I will repost in the appropriate section.
