I am a retired 56 year old millwright leader.I have owned the following CZ firearms over the years.CZ 52 semi rifle 7.62X45,52 pistol,70 and 50 .32ACP pistols,and my new 82,I have had about 1 month.I have always had a weak spot in my heart for check guns,I feel they are well designed and built like a Brick Xhit house.Very Ruger like.The 52 rifle was way ahead of its self.Power falls between a 7.62x39 and 7.62x51.I still have the black rifle and 52,82 pistol.I love the roller locking system of the 52 pistol.M60 machine gun,G3,MG42 used it also.great system.Well thanx for the welcome.and enough about me.
