Are FB3's still being sold?

[Lasermaster1977]

If so, how much? Can't find on Pangolin's website.

Is my QS that came with one FB3 capable of being used with the FB4s?

Thanks

They are indeed still being sold, as far as how much, you would have to send them a message through the "Request a Quote" button on the product page
