The rest looks like the folding stock lays on the left side of the receiver when folded and they have succumbed to the silly stuff we have slapped all over our M-4 Carbines, i.e., laser pointers, vertical forward handgrips, etc. etc..We started with a short, handy carbine that only weighed 5 pounds or so then larded the things up with "necessary accessories" and put the weight up to M-1 Garand size. Sheesh!
They have finally moved the rear sight to the rear of the receiver cover to improve the sight radius - and I will have to assume that they have gone to using a peep sight in that location. Thereby adopting what the Finns (Valmet) and the Israelis (Galil) have done for decades to improve that little beast's precision.
