I"m looking for flip up caps for a 50mm objective. The internal threads are M52 x 0.75, but there are very few resources that use thread pitch when ordering flip cap adapters or ARD's. My scope isn't listed on the Tenebraex site, but I wanted to see if there were other 50mm scopes that shared the same thread pitch. Another option would be to buy a camera adapter that allows me to use another model's adapter. Are there any resources or cross referencing objective thread pitches for different makes/models of riflescopes?
