/cgl/ - Cosplay & EGL

I'm thinking about getting an airsoft/replica M249 and was looking for some help.

Pic related is the version of the M249 used by Homura Akemi, which is the cosplay I'd be using it for. I'm not too much of a gun enthusiast, but it seems to be the Mk 46 version with the Mk II stock.

I don't care too much about exact accuracy, I just wanna make sure it's a version with the recognizable elements (belt box, tripod, solid stock). Main problem is that most airsoft versions of the M249 are full-metal and really expensive.

So really what I wanna know if there's somewhere I can find cheaper, plastic or non-functional replicas. It'd be cool to have a metal version, but I can't really see myself shelling out $300-600 for an airsoft gun that I'm gonna use as a prop for one cosplay and otherwise have in storage.
