 Question about Class 3

Hey guys!

I don't post very often... but was really curious about this.

I see things like < 16" barrels and fully auto triggers (Geissele) for sale and the site specifies "NFA rules apply."

So, my question is, what hoops do you have to jump to buy these? Say I have a registered SBR lower... what will the site do to verify that I can buy their 10.5" barrel? The fully auto trigger?

I plan on getting a registered SBR soon as was curious how hard it would be to buy the barrel. And if it's 'easy', then I'm a little surprised that someone could buy a Geissele full auto trigger and have a machine gun...

Much more complicated than that - and this will get moved. In short, you won't be buying a fully auto trigger from Geissele.

Basically it falls back on you to abide by the laws. If you get caught, it's your ass, not theirs.

Haha, thanks for the warning that it will get moved.

I was hoping for more of a detailed explanation.

As for the trigger... here is one listed on BCM:

Just curious how I buy these things. Interested in the short barrels because I want one soon. Interested in the full auto triggers because I'm just surprised that BCM sells them.

Hit up the Geissele website for details on that trigger.

The trigger group isn't necessarily what makes something auto-fire. More parts are involved. Look for the SSF Trigger on their website, and read the description thoroughly.

It is "easy" to buy the parts in that many places don't ask to see a copy of your paperwork.
To buy the SBR uppers most places will just sell directly to you just like you were buying any other upper. It is a legal item to own if you have an AR pistol or an SBR.

It's not quite that easy. You don't just drop a full auto fire control parts set into a semi-auto AR and get a machine gun. If you want to run a full auto AR/M16 then you will need more parts than just the trigger group. If you want to play the full auto game badly enough, you can buy a sear or a registered receiver (think $10k-$15k+ depending on what you want). Then you would be able to legally install the full auto fire control group in the gun...though it would likely come with a lower parts group.

Semi-auto rifle receivers are designed not to accept an M16 autosear without significant machining. Drilling a third hole for the pin is nowhere near enough.

However if the hole is drilled that is making a MG, regardless if the machinging is done or not. However you can do the machining and not drill the hole and still be legal.
