Would a long slide support an 18.5 inch barrel well enough that the gun can still cycle? I think you guys can guess where I'm going with this, I bet norinco could produce a mainspring housing with a stock, I've seen some pictures on Google and I think they look awesome, it would be a really fun bush gun in my opinion. Plus 10 round mags are definitely available. This-http://s273.photobucket.com/user/rpllvn/media/CarbKitRa.jpg.html
