Is this something an adapter could cater to? Easy to print, with a nice finish.
I have only had my tacticam to the range twice I think. Once attached to an AR-10 with NX8 1-8 and once on my bolt gun with S&B. Knowing this I decided to go and verify the information. Turns out I was both right and wrong, lol.
The S&B it didn't fit was an older full size 3-20x50. However, I just checked it on a new PMII 5-25 and it fit with the thinnest spacer installed. Apparently the ocular housing on the older PMII is significantly larger.
Discovering this, I tried it on a couple other optics I had handy and it turns out it DOES fit 5-25 Tangents and Kahles K525i's. I apologize for my previous erroneous statement.
Now, to answer your question, the entire metal housing was too small to fit the older PMII so I don't think a new adapter could be 3D printed because it has special lenses and mirrors in it. However, with the aforementioned corrections it may be moot anyway.
