Cold Harbour Jerry Converter Ring for Jerry-14, -31, -FB, RNV-14 and RNV-31

Got a little butt pucker factor when removing the rings off of the RNV-31 because I didn’t have the specific tool needed. But I managed remove them without scratching my lenses! Overall this product is exactly what I needed. Buy the tool with the adapter rings.

Great product. Easy install.

Perfect fitment just be warned if you get a protective lens for this and there’s a light source reflecting off you’ll get a double image of that light but it’s worth the trade off for my case and it’s not that bad
