Well, actually I think I may have come across something interesting here! So I know it's not the greatest amount of expansion, but I believe it could possibly be a universal expander.

It is only 3x expansion, but as far as the price point and how universal it may be, it could be our best bets. It's $60 and I have ordered from the website before a couple of times and everything arrives as expected. In fact, I would really recommend their G7 lenses. It even has pretty good shipping for China!
Basically, Podo said that if "your laser fits the star pattern caps, this BE will fit as well." And I purchased an adapter for those pattern caps that fits onto all common lenses like the 3 element, G2, and G7..... So basically, I'm hoping this could work? Thoughts anyone? I have yet to buy one just in case it won't work.
If I may ask, where did you purchase the pattern cap adapter?
