The break, the triangle folding stock, and the 90 degree gas block all scream '74. However all those features can be had on a '47.
Now it has a steel mag, but there are 5.45 steel mags out there and the angle of the pic and the curvature of the leg makes the curve of the mag hard to see, but it doesn't look curved enough for x39. So I am going to say it is probably a '74.
As for the tatoo, I would have rather put that money towards a real one instead.
