One of the few things great about living in the United States is the guns you can own

I've held a C&R license for about two years now and I've amassed quite a nice collection:
2 Yugoslavian SKS(neat rifle very well made with a grenade launcher attachment)
1 Albanian SKS(roughly made, but interesting piece)
1 Czech VZ24t Mauser(Russian captured)
1 Czech made Kar98k Mauser
1 Yugoslavian M48 Mauser
2 Russian M44 7.62x54mm carbine
A C&R license is really a great way to build up your gun collection. I do it more for historical purposes than anything...it's neat to own a piece of history that you can actually shoot. There's a few rules to having a C&R one is you have to keep a log of your collection and you can be subject to audit by an ATF Agent, but you have the option of taking your collection with you for review at an ATF office or having them come to your home to view your log book and collection. The license costs $35 and it's not a bad deal at all in my opinion.
