[QUOTE="MudRunner2005, post: 1664317, member: 12995"] I was going to do that years ago, but never got around to it. If I remember correctly, the 700 and Model 7 should be the same barrel threads. I would verify though, before dropping any money. You're barrel will have to have the tennon cut back nearly all the way to the case neck, because the CM is based on the .308 Win, and the Grendel is based on the .220 Russian (smaller diameter than the .308/CM). You will need to start with a .223 action, and have the magazine box feed lips custom trimmed for the odd-sized Grendel width. And the bolt face opened to the odd-sized diameter. Other than that, straight-forward build from there. Unless you can find a REALLY hard to find rifle, then you will have a platform that is nearly perfect from the get-go... Remington used to build the 5R milspec rifles chambered in 6.8 SPC. If you can find one those, that would be ultimate platform to start your build. [/QUOTE]
