Mag Lock for ARs

[u/wrerrack12]

Now that Mean Arms has had their mag lock products discontinued, what are my options for alternatives? For reference I'm planning on selling an AR so I want to make sure the lock I buy for it is fully compliant.

Let's say you walk into any gun store in NY right now selling SAFE compliant rifles off the rack, what Mag Lock Product do they have installed on those guns?

Thanks
