A new S-Thunder break action grenade launcher is now available through Airsoft-War4, with a package price tag of $110 USD (I hear the launcher itself is also available for just $70ish USD). What I like about is that it looks like you can put another AR-15 grip on it (like this one, I don't know for sure though), and since it isn't a replica of anything, it should be very easy to import into Canada. I'd love to see a long barreled version, as that would rock when shooting rockets etc.
