This saddle ring is made to mimic the old style rings on old lever action rifles. This is modeled off of an older Winchester saddle ring. The ring material is 0.188" diameter and the ring itself has an outside diameter of 1.125" (1-1/8"). The stud has a threaded section that is 0.20" long with 1/4"-30 threads.
The original pre-64 Winchester saddle ring Model 94 rifle used 1/4-30 pitch threads for the saddle ring. If installing in a pre-existing hole, please verify depth and thread pitch prior to install to avoid damaging your rifle.
This piece is all-blued as shown.
