Precision machined in the U.S.A., Remington integral scope mounts are constructed from quality steel and hard-coated with a matte finish for rust resistance. These integral scope mounts, which fit all Model 700 Rifles, feature Z-2 alloy construction, which is 50% stronger than aluminum. The base and lower ring, available in black or silver, are all-in-one, creating a super strong design attached by 8 TORx grade tactical screws. Fits most 700 models. 783 does not fit..
