The step of connecting the first and second mount portions together may include positioning a shim between the first and second mount portions. The step of connecting the first and second mount portions to a fixture may include clamping the first mount portion to a fixture rail. ## Claims ### Claim 1 A method of manufacturing a rifle scope mount, the method comprising the steps of: forming a first mount portion defining a first portion of a cylindrical scope tube passage; forming a second mount portion defining a second portion of the cylindrical scope tube passage; after forming the first and second mount portions, connecting the first and second mount portions together; connecting the first and second mount portions to a fixture; and after connecting the first and second mount portions to a fixture, machining the first and second mount portions to define a cylindrical bore at the cylindrical scope tube passage. ### Claim 2 (depends on 1) The method of claim 1 wherein the step of connecting the first and second mount portions together includes positioning a shim between the first and second mount portions. ### Claim 3 (depends on 1) The method of claim 1 wherein the step of connecting the first and second mount portions to a fixture includes clamping the first mount portion to a fixture rail. ### Claim 4 (depends on 3) The method of claim 3 wherein the fixture rail has the form of a picatinny rail. ### Claim 5 (depends on 1) The method of claim 1 wherein the first mount portion is a base including a clamp operable to mount to a firearm. ### Claim 6 (depends on 1) The method of claim 1 wherein the second mount portion is a scope ring cap. ### Claim 7 (depends on 1) The method of claim 1 including after the step of forming the first and second mount portions and before connecting the first and second mount portions together, treating surfaces of the first and second mount portions. ### Claim 8 (depends on 7) The method of claim 7 wherein the step of treating the surfaces of the first and second mount portions includes anodizing. ### Claim 9 (depends on 1) The method of claim 1 wherein the step of forming the first and second mount portions includes defining a registration hole in each of the first and second mount portions. ### Claim 10 (depends on 9) The method of claim 9 wherein the step of connecting the first and second mount portions together includes positioning an elongated registration pin in the registration hole in each of the first and second mount portions. ### Claim 11 (depends on 9) The method of claim 9 wherein defining a registration hole in each of the first and second mount portions includes defining a different sized hole in each of the first and second mount portions, such that the elongated registration pin is more readily removed from one registration hole than the other registration hole. ### Claim 12 (depends on 1) The method of claim 1 wherein the step of forming the first mount portion includes forming a forward scope ring cradle and a rear scope ring cradle, and the step of forming the second mount portion includes forming a forward scope ring cap and forming a rear scope ring cap, and wherein the step of machining the first and second portions to define a cylindrical bore includes machining the forward scope ring cradle and forward scope ring cap and the rear scope ring cradle and rear scope ring cap while maintaining the fixture in a fixed position. ### Claim 13 (depends on 12) The method of claim 12 including wherein machining the first and second mount portions to define a cylindrical bore includes machining the forward scope cradle and forward scope ring cap and the rear scope ring cradle and rear scope ring cap in a single machining operation. ### Claim 14 (depends on 13) The method of claim 13 wherein the single machining operation is a single pass of a cutting tool.
