If you are using our risers and the threaded holes on your mounting rings are 1/4-20 these 3 1/4" long screws will allow you to use those our risers with a Vixen style rail or plate. Make sure you measure the length of your existing screw and depth of thread on the mounting rings to see if a 3 1/4" long screw will work. Generally these work for Vixen sized rails but that depends on how the rails are made. Price includes 4 screws.
