Nope rimfire is exempt from assault weapon laws.

really? i thought there would be some rule or regulation concerning a lower that is compatible with an ar15 upper. i do have an ar15 rifle at home so im worried that possessing both might be a problem.

mmmmmmmm

maybe the rate Ca going at , we gonna need bullet button on everything..

There's nothing wrong with that. So long as you have a mag lock on when the centerfire upper is attached you are GTG. I'd suggest a raddlock if you are going to keep just one lower. It will change between mag lock and normal release with a few turns of a screw.

You can also own a nice 5.56 upper of your choice mated to a lower, both in featureless configuration, and right next to it keep another rifle with a fully-functional lower and a .22 rimfire upper on it. Push out 4 pins as needed once you cross state lines...

thinking about getting just the upper and going this way. so just to clarify, the raddlock can be on normal release when its mated on the .22 upper. once its off it should have the mag lock at all times, even if its not mated to either upper. do i have this right?

there 's no constructive possesion in regards to CA laws/

you can have one lower witha standard releease and two uppers/ Just do not mate up the centerfire unless you go featureless or BB/

thank you all very much!

This is the step that I took (conversion kit with raddlock), I enjoy using the exact rifle I shoot to train with as well, opposed to a separate rimfire AR. I just went with a lower marker multi caliber opposed to one marked 5.56 or .223, just as a peace of mind. I can see a LEO who is ignorant with AW laws harassing you or perhaps even arresting you via pc12280 (I think that would be the charge), just because your lower is marked 5.56/.223 ect. This could likely be even more troublesome with a conversion kit opposed to a complete .22 upper since the conversion utilizes the same barrel which will also likely be marked 5.56/.223, the only way to confirm that your AR has a conversion installed is to check the BCG since all marking on the rifle would be marked for center-fire use. Again some LEOs are unfamiliar with even the components of an AR BCG and may believe that you AR with .22 conversion installed is infact a bullet button less assault weapon. An easy clarification in court but a rather large hassle IMO.

that, my friend, may be closer than you would think...

[donw]

my spikes ST-22, a dedicated .22 lr AR, has the lowers stamped ".22LR".

when i have the 5.56 uppers installed, i do have the BB installed!!!

Nope rimfire is exempt from assault weapon laws.

*bzzt* WRONG.

Rimfire handguns are very much still subject to assault weapon laws. The ruger charger without a magazine lock is an AW in CA. Rfiles aren't an issue, but for handguns it is. So while the OP doesn't need a bullet button, to say rimfire is completely exempt is incorrect.

Why get the raddlock if you already have a bullet button installed on your gun? Just go get the Mag Magnet. There are a few different ones out there that you can get and it's a lot faster than moving a screw in and out if you are at the range and decide to switch uppers.
