I have 3 sons and they all shoot Brno rifles in 7x57. One rifle is a model 21 carbine, a model 21 rifle and a model 22 full stock carbine.They also made a full stock rifle. I still see a few of these guns at the gun shows. I have only saw one with the original scope and rail base for sale and the price was high. I owned a 9.3x62 and it kicked harder than my 375 ZKK 602 so I sold it. I also had a problem getting brass and bullets. I still wish I had kept it.
