This 2000's dated 700 has been rebarreled with a stainless brush finished extremely large sized bull barrel chambered in 6mm BR (barrel marked 6 BR.x.277 NK.) Barrel is of unknown mfg. It looks like the stock is a McMillan, even though there is a Remington buttplate.  There is NO SAFETY on this action and a very fine hair trigger, Don't sneeze, scope, but the installed mounts are included.
