I have one of the M69 rifles from tradeex. I find it to be a very well aet up rifle and my most accurate "irons only" rifle. It has shot 1 moa at 100 meters on a day where I was doing my part with some old Privi ammo. 6.5x55 is easy to make work with handloads either way you go. The m69's are built off of captured german M98's and are #### on open. They may or may not have matching bolts, but as the rifles were built back up with trigger jobs and new barrels. Cg63 is based on the #### on close M96 mauser action. Some minor alterations were made to improve lock time by lightening the striker assembly. Functionally they are two sides of the same coin. The 9u action... gas handling superiority yada yada yada. The m96, swedish steel yada yada yada. Both actions will run a 6.5x55 well. The barrels likely came off the same assembly line at Husquvarna/gustafs. If you want to modify it, in the long run go for the 98 actioned M69 as aftermarket support for the german mauser is good and gas handling is superior to the m96.
