UPDATE: The 2nd and 5th pictured seem to bottom side fired.
Some new mechanicals have just went live on fasttech. These are top button firing and come in many different styles. Looking shape and materials used - these are on par with something like the Sigelei #8 or Smoktech Natural. The obvious difference is the button location.
These will work with 18650 batteries, 18500 w/ a kick, or stacked 18350s.
These are located at the a few rows down on the page.
