A quick look at the the Arrow Arms APC9-K Folding Stock AEG that Gunfire got in stock at their store... "Arrow Arms knows what airsofters like the most. Introducing the APC9-K Folding Stock to the market perfectly fulfilled our needs. A small, neat SMG, made of metal and polymer, is a real monster in tight corridors. In places exposed to damage, the manufacturer used metal, and where it was possible to cut weight, he used a polymer. The APC9-K features a slim motor, a proven V2 gearbox, and the praised EFCS system, which significantly improves the shooting experience. An additional advantage is the three magazines that can be found in the box."
