300 Blackout AR15 Pistol

[Hippoyell]

Hello, I'm guessing I'll get flamed for posting this, but I used the search function and couldn't find my answer. Once I have an answer I will delete the thread (assuming I have this capability).

Okay, I am wanting a 300BO pistol. I understand I cannot buy one from out of state any more, it has to be a face to face transaction. However, these are far too spendy now due to the fixed supply.

I am thinking about machining one from an 80% lower that I already have. Is this legal? If so, what hoops do I have to jump through, like putting a SS sled in it, etc?

Sorry for asking something that I bet has been more than adequately addressed. I couldn't find the answer on my own.

No hoops if it's an 80% and it's totally legal as long as it's for your personal use.

[Hippoyell]

Thank you so much for the reply. So I don't have to buy a single shot sled, or have any proof like pictures or whatever that I made it myself on certain date, or anything?

I can just straight up build a 10 round pistol with BB?

[JDW67]

Yes, that's the point of the 80%.

Not legally.

In order to be legal, the "80% receiver" needs to be made into a dimensionally compliant bolt-action single-shot pistol or into a dimensionally compliant break-top/open single-shot pistol. [PC 32100(b)]

In other words, yes. He can straight up build a single shot pistol that has a BB.

No, it is not that simple. Please don't post answers to questions when you don't actually know the answer. Somebody could end up in legal hot water if they follow bad advice. There are many nuances in the way this law is written. And if you don't go through all the correct steps, you could risk your gun rights for the rest of your life.

OP, as Quiet noted, you have to follow the exact letter of the law. You can build a single shot handgun that is either bolt action or break action. That means a 0 shot sled. That also means you have to disable the gas system somehow. The easiest way to do that is to omit the gas tube when you build it.

As for documentation with pictures and such... I know that sounds like a great way to protect yourself. However, it is up to the prosecution to prove that YOU did it wrong. It is not up to you to prove that you did it right. Pictures can only serve to incriminate yourself, as they provide photographic evidence. What if they are able to measure the length in the picture and it is too short? Or if they decide that a particular brand of 0 shot sled doesn't count? You are providing evidence for them. Far better to simply build it right, and leave it at that. No pictures. And the prosecution has nothing to dispute what you say. After you have built it to be compliant, you can do whatever amuses you with it. Including making it a semi-auto with a 10 round magazine. As long as it meets the AWB laws, you are fine.

OP, MB is correct.

[Hippoyell]

Thank you for the thorough response.

I'm guessing there are resources that outline how to do what you're talking about. Would you mind sharing them?

Thanks for your time.

He just told you what you need to know. I have seen three threads about this this week. Use the search function for ar pistol. You would literally build it with no gas block at all and a sled and be gtg.

[BigPimping]

Just buy a registered pistol lower. Don't cheap out.

[Hippoyell]

I would love to, but I'm not BigPimping, I can barely justify doing this from an 80%er to the wife

Because the firearm can never had been semi-auto prior to creation, you will need to build your own upper, instead of buying an existing upper and modifying it. This is because existing uppers are typically test fired by the manufacturer as a semi-auto.


In addition to installing a maglock & 0 round mag/sled, the following must be done depending on the type of upper...

If the AR style pistol normally operates via direct impingement, then:
1. Do not install a gas tube.
2. Do not install a gas block or plug the gas block.
This makes it a straight pull bolt-action single-shot.

If the AR style pistol normally operates via gas-piston, then:
1. Do not install a gas piston.
2. Do not install a gas block or plug the gas block.
This makes it a straight pull bolt-action single-shot.

If the AR style pistol normally operates via blowback, then:
1. Install a dowel in the buffer tube, which prevents the buffer from moving.
This makes it a break-top/open single-shot.
