Hey guys, I am looking at building a custom rifle from the ground up, piece by piece. I want to base it off of a Remington m 700 action, so where can I buy one of these? And any suggestions for barrels, ect.. Are greatly appreciated. I want to go with a hart barrel, looking at building it in a 300 ultra mag. And once again, suggestions from all you out there are taken seriously! I want the most accurate rifle I can build. Thanks!
