Wow. I knew that Amazon banned firearm sales (makes me sad), but they have some stupid arbitrary rules.

Prohibited: Single point, 3-point, tactical, and quick detach slings

Why? seems like slings can be used for many things.

Permitted: Fixed stocks, with the exception of thumbhole stocks

Prohibited: Any non-fixed stock, including telescoping, folding or collapsible stocks

Someone please tell me why non-fixed stock are so horrible?

Permitted: Magazine floor plates/base plates

I'm actually surprised by this one.

Prohibited: Full auto sears (also known as drop-in auto sear or DIAS)

Haha. Amazon would be the least of your problems if you sell one of these. They should also probably stop selling metal coat hangers.[1]

Prohibited: AR-15/M16 armorer’s wrenches or combo wrenches

Really? So I cannot by a castle wrench if it's marketed as for AR-15s?

Prohibited: Magazine loaders, except for those that can accommodate the following calibers: .223/5.56; 7.62x51; 308; 7.62x39; 5.45x39

Okay but .300 AAC, 6.5, 30-06, .338, .50 BMG/Beowulf are fine.

So much irrational hate for the AR-15 platform. It should be right up HNs alley as it is a fully customizable and reparable platform unencumbered by patents.

I don't know why you're worried about sears because either they are unregistered and illegal or registered and covered under the firearm sale ban. Adjustable stocks are arguably a concern because they make building rifles shorter than 26 inches easier. I'm not going to comment on anything else and I'm not pushing any specific agenda with this post, but those were my initial thoughts about those items.

Exactly.

You could just not put stock on. An AR-15 with a 16in barrel is 30in with the stock collapsed and cannot be much shorter without the stock because of the buffer tube.

>An AR-15 with a 16in barrel is 30in with the stock collapsed and cannot be much shorter without the stock because of the buffer tube.

Telescoping stocks maybe not (my inexperience showing there) but folding stocks definitely can take it under 30 inches then. I assume you're saying a normal caliber ar15 won't be very fireable without a buffer tube. Anyways, apparently folding and telescoping stocks are also illegal in California, which might be the real reason amazon has these rules.

While there are technically stocks you can get for an AR-15 that fold, because you have to also fold the buffer tube they are not recommend and potentially unreliable. It is completely inoperable without the buffer tube.

They are not illegal to own in California. They are only illegal to be on a semi-automatic center fire rifle with a detachable magazine. So if you mag lock your AR with something like this[1] you can put a telescoping stock on it. This is also legal[2] (with a 10rd magazine) since it is not a center fire rifle.

Again a stock is not integral to the operation of most rifles so you can just not put one on. Oh course then it's legally not considered a rifle most of the time.

Moreover, having a rifle shorter than 26in is also a federal crime. You might as well go all the way and saw the barrel in half too if you really want a SBR.

I'm familiar with mag locking and all of the "featureless" difficulties, I was just being brief. However I understand center fire refers to the cartridge/primer configuration and I'm not really sure why that matters, could I trouble you to explain? WRT the buffer tube, I understand that you need the buffer to move the bcg, correct?

Sure. It matters, I'm guessing because the design prohibits larger calibers due to the physics of how it works.

>Rimfire ammo is limited to smaller calibers since the cartridge walls need to be thin enough to be able to be crushed by the firing pin and ignite the primer.

> The downside?

> Well, the nature of the casing means it’s pretty much limited to small calibers. You have to have some relatively flimsy brass to handle the rimfire set up. As a result, the powder necessary to propel a larger bullet would blow the brass apart.[1]

Correct about the buffer tube. So even if you installed a folding stock on an AR-15, it require some proprietary buffer tube to work like this one.[2]

Oh, that makes a lot of sense. Thank you for your time and knowledge.

You're welcome.

Maybe they're following certain state laws regarding online gun accessory sales? By certain states I mean NY, CA, and naturally WA.

There are many items that are permitted but subject to geographic restrictions such as airsoft guns.[1]

Aside from actual serialized firearms, ammunition, magazines, and some triggers in some state, pretty much every state has no restrictions on firearm accessories such as stocks, grips, slings, sights, and even barrels.

Funny, I just received a VTAC sling from Amazon. I wonder if I was able to buy it due to the "enforcement failures" mentioned in the article or if it's because it is a 2-point sling (obviously much safer than a single point or 3-point sling which are basically weapons of mass destruction).

I haven't checked, but I wonder what their policy is on "inline fuel/oil filters" and "solvent traps".

According to this article https://www.guntrustlawyer.com/maryland-man-arrested-fuel-fi... they have been sold on Amazon before. If they are considered a silencer by the ATF then it would fall under Amazon prohibition on selling silencers.
