A friend of mine purchased this gun under my recommendations. The version he bought was the CYMA ak - fake wood (no rail, just the gun)
The weapon is heavy - and the metal construction is not aluminum or pot metal. It must be a low grade steel - you'll see it when you buy it. It isnt awesome, but hey, its a step up from the old crap metal bodies chinese guns used to offer.
Flash hider is accurate to the weapon - not the plastic cap that comes with other models.
Mag wobbles a little, nothing dramatic.
Stock is the biggest issue, as with all chinese ak's. The screws come loose VERY quickly. LOCK TIGHT!
The piston grip and other plastic components are nice, they arent great but they arent flimsy. I am not willing to vote that they are nylon fyber or polymer... just textured ABS.
Internals: The gear box is a CYMA version 3 with 7mm metal bushings with odd grease ports. The gears are standard ratio, decent steel with grease ports. Nothing fancy really. Spring guide is a cheap plastic - Piston in a reinforced plastic (I still recommend polycarb) and the piston is a 4 ported, no bearings head. Cylinder head is plastic with one o-ring. Motor has solder'd wires, so remember that if you plan on rewiring the weapon. Motor produces a decen 11-12 bbps and the fps was around 390 for ours with G&G 20s.
Price for when we bought it was 154 (had no rail or trademarks,)
Reliability: CYMAs work if you just treat em right!
Internal build quality has improved
Looks - they are paying more and more attention to detail now.
Piston and spring guide are a bit.. meh
stock screws come out.
Chinese... I know.... that is always a con.
