'best' AR pistol lower receiver?

I have all my lowers marked "machine gun" ..........................

"You assume that anyone who might question you actually knows the law. Having "pistol" on the lower doesn't define what it is."
Actually, the opposite.
The reason people are looking at the sig brace with interest is because it allows you to have a sbr while technically not having one. Many of the people here were surprised by the atf decision.
So, when someone unfamiliar with the ruling sees a person with a normally illegal sbr, having the weapon or yourself detained is a very realistic possibility.
Having it marked as a pistol, and carrying a copy of the atf ruling is good judgment, especially considering the lack of knowledge with these specialized issues by law enforcement.

Not sure if serious, or trolling.
The SB-15 has intended use on a pistol, for use on pistols. The BATFE cannot legislate shooting positions used for firearms, but it is a legal component for installation on a pistol per their judgement.
Somebody unfamiliar with rulings shouldn't be making a felony stop, or if they do, you still own a pistol and are at most out the inconvenience, frankly nothing relevant about that.
Whatever they look like, an AR pistol configured as an AR pistol is - a pistol. SBR specifically refers to an NFA weapon built on a Form 1 (often transferred over a Form3, but all SBRs have a Form 1 somewhere in the past), so the term in this context has a precise definition you're using incorrectly.

If you're still worried, you'll be hard pressed to have a better excuse to throw on some custom awesome engraving along with adding engraving with PISTOL in enormous letters if that helps, hell, make a 80% upper and add that yourself. The markings peculiar to a given lower receiver only have any relevance whatsoever if this is an NFA item, otherwise any stripped lower works fine. If you're worried about somebody ignorant assuming you have an SBR, then don't put anything on it that looks like a weapon a free state resident with $200 and some patience would own.

Not to derail:

I do agree that some LEO's are unaware of even state gun laws. I was pulled over and told that the G19 under my seat was an "illegally concealed weapon".

OP:

I believe that the SB-15 must be installed on a Pistol Tube. Therefore, no it can not be used on an A5 extension.

Furthermore, I think the use of a Pistol Tube (vs. a bare receiver extension) would more clearly indicate your intended use as a Pistol vs. merely having "Pistol" engraved on the side.

I have also been told that a bare receiver extension is not acceptable on a Pistol. However, I think this may be incorrect.

Can anyone clarify?

All things I already covered. Yes it will not be key in a final legal ruling, but there is a significant chance it could be key in a minor or major inconvenience, including you and or your weapon being detained, or being charged with something that will eventually be dismissed.

Every owner should plan ahead in the event they need to explain why their, by all appearances SBR, actually is not..........at least it would be smart to anticipate the issue, which is why carrying a copy of the ruling is advised.


The vast majority of police departments probably have no patrol officers or supervisors (in the entire dept let alone working the road) that are familiar with this and the specifics involved

And it doesnt just avoid the federal issue, the state laws are also at issue.


Anyone that doesnt see a benefit is unfamiliar with law enforcement

You mean anyone stupid enough to actually think having a lower marked as pistol somehow means anything.

But, to add to your comment, no, there are others. Aero Precision is one of them.

Actually, it's been clearly explained that anyone with the slightest knowledge or experience concerning the way law enforcement works would see that having it marked as a pistol would significantly reduce the chance of a person and /or their weapon being detained.

The only people that would disagree are the uneducated, inexperienced, or kooky sovereign citizen types

You are making plenty of assumptions. Most LE are only worried about stuff like that when the person in possession of it has done something wrong. It is clearly established that a stripped receiver is marked as "other" and can be made into either configuration.

Most LE have very little knowledge of anything more than cursory gun laws. I.E. the obvious shit like having a machine gun, suppressor, sawn-off shotguns, etc...

I travel all the time with firearms and no one even gives me a second look. Additionally I don't let people randomly search my vehicle and I don't volunteer information so it's also moot.

Actually it seems very obvious , when you are potentially questioned about your normally illegal sbr, and you have to explain that it is actually a pistol, it will be extremely helpful to have the receiver labeled as a pistol

[Iraqgunz]

And he could just as easily say that you were in possession of an SBR and you used a pistol marked lower to attempt and conceal the issue.

Actually, it's been clearly explained that anyone with the slightest knowledge or experience concerning the way law enforcement works would see that having it marked as a pistol would significantly reduce the chance of a person and /or their weapon being detained.

Do whatever makes you happy. You are mixing up too many other issues into this whole process. If I was you I would also not get a Sig brace so some LE guy doesn't think you have an illegal weapon and arrest you.

First its a new issue, quite different than the appearance of the unusual pistols with the buffer tubes sticking out the back, and legally it wont make a difference
in the long run.

Where it likely could make a difference, and im basing this on a lot of LE experience, is dealing with many cops who often make mistakes interpreting
strait forward laws (DV vs community property, assault, etc.....ive seen a lot of crazy/bad arrests), is when/if a cop is making the decision to detain you or your weapon.
And since this wont be an approved NFA item, that means it will not have that umbrella and will instead be evaluated under each state's laws.

My educated estimate is that having it marked pistol would reduce that chance by about 30%. Combine that with a copy of the ruling in your case and you are
probably at about 50% less likely.

But I plan ahead, I carry a copy of the LEO safety act with me when I travel.

It is a smart move, anyone denying that just doesnt know how law enforcement works.

*it slightly reminds me of the gun trust issue, getting a trust from online or the gun store for $50 will probably go through and get approved, but its issues down the
line, death, etc, etc, that make a reasonably priced gun trust a smart choice.

People either plan ahead or they dont.
