I heard that they are solid chunks of metal but not don't feed particularly well with specific brands. Also, unless you have a WWII loadout, you won't look the part with it.
hmmm, how i see it is that WWII guns don't go with modern day kits like desert camo, dpm and multicam. Maybe a thompson would be okay.
Modern guns are everywhere, why conform? I would have bought a WWII gun recently but I'd rather wait until G&G start producing them
