As I was doing my airsoft routine of checking every airsoft web site that I know of for new and cool shit that slings bbs ... i stumble into this badass piece of hardware ... (now i know what your saying "cory your an RPG-7 fan why this") I'll tell you ... the AIRSOFT RPG-7 requires that you remove the warhead to actually fire a 40mm airsoft grenade and that defeats the purpose of an RPG-7 ... soooo this thing supposedly fires a 40mm shell while still looking badass .... just sayin.
