This weapon should come back. Not as an smg though. My thought based on SR4e:
Ak-97 Carbine (assault rifle)
Acc 5, DV 9p, Ap -2, Mode SA/BF/FA, RC (1), Ammo 30(c), Avail 4R, Cost 850¥. Folding stock. Conceal +4 with stock retracted. Not quite sure of the price or the range. And maybe DV should be 10P. Sound reasonable?
