Product Description
If you are using our riser blocks and your rings are 6 mm, these M6 X 80 mm long screws will allow you to use those Chinese rings you have with the metric thread. Make sure you measure the length of your existing screw and dept of thread on the Chinese rings to see if an 80 mm long metric screw will work. Generally these work for both Losmandy and Vixen size rails but that depends on how the rails are made. Set include four stainless screws.
