If you stick a 22LR mag in your multical complete lower, do you need a bullet button?

[Cool Hand Luke]

Being a little bored, I was thinking of building up another lower. I am not sure if I want to put a 7.62x39 upper on my multi-cal marked lower or a dedicated 22LR upper. If I slap a 22LR BDM mag in the lower, can I legally put a retractable stock and a pistol grip on it, and forgo installing a BB unless I decide on a centerfire upper?

the "evil" part restrictions are for centerfire and 22lr is a rimfire so you can use a standard mag release, flash hider, adjustable stock, front and rear pistol grips. put the BB back on when the .223 or 7.62 upper goes back on.

I say you get a Rad lock on your lower, that way you can go from BB mode to normal mag release mode with just a few turns of the Rad lock screw-tool-thingy. Its a genius design.

its a lower, not a semi auto centerfire rifle, so its legal without an upper, but then again im not a lawyer

this is the way i interpret as well. there is no constructive possession in CA, so without a semiauto, centerfire upper; a lower is just parts.

Ditto.
The upper is the key.

You could slap a 7.62x39, or a 5.56 magazine into the magwell and as long as there's no upper attached, you're 100% legal.

Same for a stripped upper.... no barrel and no BCG, that upper could be anything. It is not semi-automatic without a gas system (and bolt), and it is not centerfire without a barrel or BCG.

so then theoretically you could buy a complete stripped lower w/o BB legally right?

[PyroFox79]

ya if its stripped then it wouldnt have anything on it...

This is 100% legal without a BB... if it weren't, I certainly would not be posting a picture of it.

I would get Lower with marked multi cal

Exactly. I was always under the impression that a lower with a pistol grip and/or a retractable stock was leaning toward the illegal side. I assumed this because I have never seen a vendor sell a complete lower w/o a bullet button. Are people now selling complete lowers without BBs?

They will, but not often... Usually, people want to pick their own grip and buttstock.

Riflegear has been offering completed lowers for quite some time (lower with LPK installed, no buttstock). The bullet button is optional. No reason to spend the $25 for it if you're building a 22lr, or a bolt action (standard upper with a disabled gas system)

There is no "leaning toward the illegal side".... there is legal, and there is illegal.
Illegal is a semi-automatic, centerfire rifle with any of the SB23 features and a detachable magazine.
If any of those 4 are missing, it is 100% legal without question.

A completed lower, without an upper attached, is neither semi-automatic, nor centerfire, therefore, it does not require a fixed magazine.
