The KM, or Keymod, rifles from Classic Army are members of their Skirmish series. These rifles feature a strong but lightweight polymer body and heavily upgraded internals right out of the box. They also blow everything else out of the water at their price point: under $200.
The KM10 and KM12 have 10-inch and 12-inch keymod rails, respectively. Each of these guns also has an additional 2 inches of barrel poking out from under the rail that terminates in standard 14mm CCW threads for attaching the flash hider or suppressor of your choice. This rifle is also compatible with most standard AEG pistol grip stocks.To sum up how well priced this rifle is for all its features, we at Fox would charge $150 to install a good MOSFET, a precision tight bore barrel, and Dean connectors with labor. With how upgraded it is out of the box, it's practically as if you're getting this gun for under $50.
