What Ruger 10/22 is this?

I can’t seem to find a 10/22 similar to this one. Any thoughts?

Grock says it's a CST receiver. Custom Shooting Technologies. I never heard of them.

Brownells sells a 10/22 receiver with the rail integrated so does black rain.

Are they normally marked like this?

Musk named it after the word Grok from Heinlein's "stranger in a strange land".

It basically means "to understand something".

Ruger’s serial number lookup says that s/n does not exist. Might be a clone knockoff.

I have one of the Brownells rail integrated BRN-22 receivers, it needed a small amount of tinkering to make it work but it's great.

80% sent out for laser (or other) engraving.
I've seen AR lowers done up with all sorts of vintage markings: One of which was a clone of a Colt SP-1 and if you didn't run the numbers through Colt and/or didn't know exactly what you were looking at, you'd make an expensive mistake.
