Arcturus airsoft rifle series is very solid. Adjustable hopup, microswitch trigger (11.1v recommended), 6.02mm tightbore barrel, lots of rail options, and a quick-change spring gearbox.  Includes sights and 2 AK magazines (one 130 rd midcap; one 330 rd hicap).  Can use all standard AK style magazines (midcap or highcap, drum, etc).  We're very impressed with this gun series and recommend it.  

Awesome AK12 specific folding stock - once folded, you can quick-change the spring in its gearbox!
