Everything is painted black.
The "D" in the D 70 does have a little tail in the middle of the vertical part of the letter.
There is also a smaller "D" laying down that almost looks like a "B" but doesn't have the round roll in in the middle. This is at the end of the D 70 mark.
The charging handle is folding, the furniture is all black pebble plastic.
I don't see any British proofs of crown mark. There is a "22" twice just below the gas tube.
There is no mag.
