View Full Version : CZ 452 and Ruger 17HMR Barrel Profile

May 15, 2010, 08:18 AM
I am away travelling at the moment and am looking to buy a couple of accessories for my CZ 452 .22 and my Ruger K77/17-VMBBZ .17HMR (the grey heavy barrel one). Since I do not have access to my gun room or measuring tools can anyone tell me the barrel diameter at the muzzle for these two rifles (in mm and inches)?
