Should a 22LR AR-15 upper be featureless?

[newStar]

I am looking for a dedicated 22LR upper to share the same AR-15 lower, something like below from PSA:

The question is that should I have to replace the flash hider on this upper by a muzzle brake to be legally compliant?

Thanks

Rimfire semi-automatic rifles can have all of the evil features. There's no need to change anything to be compliant. Flash hiders, pistol grips, vertical foregrips, adjustable buttstocks are all acceptable items on a rimfire semi-auto

Wow, glad to know this! Feel like in liberty place now.

Can larger than 10rd magazine be used as well?

Not with rimfire unless it is tube magazine or you have a Freedom week or pre-ban exception.

Feature-rich dedicated ARs are fine. Just be careful not to attach a 5.56 or other upper to it by mistake.

That is the reason why I had two .22LR pistols and twenty .22LR rifles.

Only rimfire rifles are exempt from CA assault weapons laws.
Rimfire handguns are not exempt from CA assault weapons laws.
