Making Rifle CA legal

[bwiese]

They can't send both halves to the ffl?

Shouldn't.

With no upper, it is possible to argue the lower isn't a 'centerfire rifle'; that's hyper-technical, but it's possible to mount a bolt-action upper or a .22 conversion upper, so with NO upper the lower is in an indeterminate state.

But if someone inadvertently assembles a semi-auto centerfire upper to that lower, before the mag lock is installed, there is a Problem.

Quite a few competent EBR FFLs have arrangements with COMPETENT out-of-state suppliers or intermediaries - such that guns are broken apart in various ways and shipped to the CA FFL, who then installs a BB before reassembling the gun into CA-legal form.

So on rifles like the ACR, SCAR etc that have serialized uppers it would be completely legal to ship only the upper to the FFL for DROS. And then its up to the buyer to make sure everythings legal before assembly correct?
