AK Grip with CA Compliant Model

Copy of a standard AK grip and it uses a standard AK grip screw. I suggest use of a washer below the screw head.

Included is a CA model with the thumb blocking piece that locates in 2 slots on the back of the grip and is held in place by the grip screw.

The CA model needs supports for the slots, but the rest of the parts do not need them. I printed it as it imports.
