Silencer with foam
Hi, I just bought a Gemtech G5 silencer at Airsoftparts.ca and I read on Madbullairsoft.com that there was a Tawain version with foam and an American version without foam, since it's prohibited. So I was wondering what the foam is doing on an airsoft replica. It can't muzzle the sound since and airgun doesn't make sound from the barrel (compare to a RS). So what's the point? And why is it illegal in USA? Can it be use to work with RS? Thank you
