M&P 15-22 why no bullet button

[RuskieShooter]

so if i wanted to build an AR platform, i wouldn't need a BB as long as it has a .22 upper?

I'm not an expert by any stretch of the imagination, but here is what I have picked up lurking:

1) An AR with a dedicated .22lr upper is good with no bullet button.

2) An AR with a "conversion kit" may be questionable as it is still technically a .223/5.56 upper and can be converted back.

3) A lower with no upper specifically marked as .223 or 5.56 (marked "multi-caliber" is ok) may be an issue.

Before I get flamed for 2 and 3, let me explain that there is no verification that these are illegal and, in fact, probably are not. However, do you have the time and money to be a possible test case?

I decided to bypass the whole thing and bought an M&P 15-22.

No, it's still considered to be a centerfire rifle

Does it fire a centerfire cartridge in its current configuration? If the answer is no and it fires a rimfire cartridge, then a bullet button is not needed. What the lower says is completely irrelevant.

Consult the flowchart.

Sure about that ?

yeah, got a nice 10/22 for plinking but also want a tacticool .22, so i've been toying with the idea of building an AR lower and purchasing a dedicated upper when finances permit next year. nice to also have the option of converting it to a centerfire SHTF rifle down the road..

I think the problem with making your own .22LR AR is the markings on your lower. If it's marked anything other than .22LR it can still be considered a centerfire rifle.

I don't think so. Your dedicated AR-22 cannot shoot centerfire cartridge so why would it be considered a centerfire? You logic is flawed because the markings on your lower does not determine the caliber of the rifle. What your rifle actually shoots determines that.

When the lower just says "multi" that could mean anything other than caliber... multi- dimensional, multi-level marketing, multi-faceted

Any RIMFIRE RIFLE is exempt.. Caliber is not as important as it being rimfire...

2) An AR with a "conversion kit" may be questionable as it is still technically a .223/5.56 upper and can be converted back.

Bwise has warned about possible issues in the past...

3) A lower with no upper specifically marked as .223 or 5.56 (marked "multi-caliber" is ok) may be an issue.

That is absolutely not the case... For example, a complete lower with NO UPPER attached does not need a bullet button. You need a bullet button if you attach a CENTERFIRE upper to it.

The upper being marked has nothing to do with anything... Thats like saying a dedicated upper that runs and is chambered for .22LR is questionable because its not marked. How is it questionable?

Markings on Uppers / Lowers are not important... Now, there is an argument when factory markings is valid... But its for magazine caliber/capacity and NOT related to what upper/lower you have... Even that only apply's to cases like running 30rds of .223 in a 10rd .50 Beowulf mag...


2 out of 3 is close...

This is correct. Also (as I was corrected on) its not so much that rimfire is exempt, its that the law specifies centerfire and makes no mention of rimfire. A subtle difference, but a difference none the less.

Bwise has warned about possible issues in the past...

Some others have speculated on it as well.

As I stated above, its probably not illegal, but do you want to be the test case? I get paranoid living in Santa Clara county (not very gun friendly). If I were going to run a dedicated upper, I would always make sure the two were attached when transporting to avoid any questions/confusion from LE.

Or like saying that its probably not illegal for me to buy a used G19 barrel or slide and use it in my gun... because the barrel has a serial number on it that would differ from whats on my actual gun.

Of course its not!

Rimfires are exempt from the California AWB, but California magazine laws still apply.

rimfire semi-auto pistols are covered under the AWB in certain cases; no threaded barrels or forward mounted, vertical, pistol grips, etc

i purchased a new, dedicated, 22lr, MSR (AKA- 'AR' ) the ST-22, from Spikes tactical thru Faith Armory's FFL with NO BB...the lowers are marked "22lr"

when installing CF uppers...BB IS required and the 10 rd mag capacity IS applicable...

Threaded barrels are ok as long as they don't have a detachable magazine. Also of note is you cannot have a detachable mag outside the grip.
