I don't know about the legality of the launcher itself (never looked into it) but having the lugs on an "other" is fine.

While I believe this is a valid concern, I don't think there is a single person on this forum, or even in the state, who can answer this. It will come down to a prosecutor, your lawyer, and a judge to determine what any of that means.

Another point I didn't mention is that FFLs don't have to worry about constructive intent. Just don't sit around with a short-barreled upper without having your vertical grip and lower ready to go is the gist of it. If you don't already own an AR rifle you probably have nothing to worry about.

I know this isn't the answer you're looking for, but if you have all of the parts picked out and understand the requirements for an other just build it yourself. It's not illegal, the state police just don't want people getting jammed up for not knowing the law. As far as I'm aware, having an FFL assemble it for you is no different than doing it yourself--both a stripped receiver and completed other are both simply "firearms" in the eye of the law and will transfer nearly identically. The (hypothetical) benefit of having an other such as the Troy is more about law enforcement familiarity should you ever get stopped.

If you use any 12.5" upper with a VFG and any pistol lower you should be fine. Several people have gotten 12.5" uppers from B. King's which are inexpensive but solid, I'm sure there are more premium options as well. If you want a shorter barrel you'll need to be a little more careful about your choice of receiver extension. Beyond this the build is the same as any other AR-15.

I'm honestly not sure. If you want to do that it's probably a better idea to use an A5 receiver extension which is a bit longer than a standard carbine extension. I believe that would allow you to use a 10.5" barrel without a pin and weld, but I'm not positive. With a normal tube you should be able to use a 10.5" if you pin it. Someone posted a chart a while back that summarizes it well.

Also, don't use a folding brace adapter, otherwise you'll have to fold it when you measure. Basically, measure it from the smallest configuration.

End of the buffer tube. That's a recent change from the ATF.

There has been a constant stream of misinformation and misunderstandings since the Shockwave etc first started getting sold in NJ. If you choose to build, make sure you understand the NFA and what makes something not a rifle or pistol. Just like you should understand the NJ AWB if you build a normal rifle.

There is no law saying that you are not allowed to. NJSP is concerned about people accidentally breaking the law and told FFLs to only sell them as a complete firearm. Many here have built their own.

Though if someone already bought a lower and the FFL didn't record it as "other" I'm not sure that's their problem. The FFL screwed up, marking it incorrectly doesn't make it a rifle or pistol. If they transferred a rifle as a pistol it wouldn't turn you into a criminal for buying without a permit.

I seem to remember something with KAK being told 13.5" was the max. The SBA3/4 only use the first 5 positions because of this I think. But then again adding a folder (on a pistol, not non-NFA) would extend it past that number too, I think.

I'd be a little hesitant using an extended/VLTOR A5 tube. Isn't there a LOP limit for braces to be considered legal? Otherwise this is a great resource.

I'd pump the brakes, some people on other forums dug into this post and can't find it, so they think it's either fake or he's deleted it. Supposedly he's also been saying this for years, yet here we are with braces still legal. Also, just because Obama was a failure doesn't mean he wasn't trying. Attempt to ban green tips, villainization of legal gun owners after high profile events, etc. Politicians all suck.

This whole thing is an exercise in how this isn't true. The law bans a very specific class of firearms--if it doesn't fall into that, it's legal. People love ribbing Californian gun owners but at least they are always trying to work around their laws with things like the bullet button. Anyone here suggests anything that doesn't have a stamp of approval from both NJSP and Evan Nappen and it's definitely not legal, like some sort of Stockholm syndrome. Also, I have to imagine you're exaggerating, but if the average experience at Range 14 is LEOs checking if your guns are legal, remind me to never shoot there.

Yes, why wait for the politicians to strip our rights when we can do it ourselves? If you want one, buy one or build one. If a cop is inspecting your firearms in NJ you're already in bad shape, regardless of what kind you have.

Who are the wrong people? Why would "the wrong people" specifically want this firearm that probably everyone on this forum acknowledges is marginally different than our existing rifles? The reason it was hidden is because while Det. Sgt. Bloom might be on our side, it's still within the context of a nanny state.

I've heard that length mostly affects accuracy due to harmonics (once barrel length exceeds some minimum length). A long barrel with poor harmonics might perform worse than a shorter barrel with better harmonics. I've seen arguments and data for both points of view. For 5.56 I don't think there is a huge difference between an 11.5" and 20", though.

Oh, I totally see one in the distant future. But who wants to wait...

I think for most people here it's about sticking it to the state. We have no hope of changing the law and no hope of a Supreme Court ruling so we do what we can.

I understand that part, I just don't see where this letter says it needs to be remanufactured by the FFL. It simply says cannot be "assembled" by an individual. And whether this actually is supported by the law is another matter.

Reading it again, it only says assembled, not manufactured. And sold "as a complete product". I don't see anything that would require it to be remanufactured.

So I bring my upper to an FFL and have them put it on my lower... Are FFLs supposed to stop selling stripped lowers too? They fall into the same category ("firearm") and they are NOT equipped with the required features in the letter.

As far as I know, you cannot start with a pistol or a rifle, but I could be wrong. But it should be easy with a new lower receiver. Build the lower, put a VFG on an upper (before putting it on the lower), mate the receivers, and you're good to go. I'm sure someone will bring up constructive intent but that could keep you from doing a normal rifle build in NJ.

Maybe I'm confused, but doesn't a FH add 1.5" to the barrel? So if 10.5" barrel + FH is only 26.3", then an unpinned 11.5 will be just shy of 26 at 25.8? Yes. Though it's uncertain whether length is measured from the fully extended position or not, so might be worth playing it safe and going from the collapsed position.
