I have a gen2 model, haven't shot it yet. Got a 20MOA rail and TPS rings from AB Tac Rifle, mounted a NF 8-32x56. The only beef I have with it thus far is the magazine fiasco which will hopefully be rectified shortly (or I will swap the stock and metal for an A5 or AICS). I actually bought this gun as a long range hunting rig, rather than as a range/target rifle. Hope to take it out when I am feeling better.
