Tech index -> Invert Mini

The Invert Mini has become quite a popular marker since it was released in 2007. Minis feature a very small body size, making a lightweight setup, as well as a simplistic design that employs no hoses and minimal parts. As with most other markers, it also features a high rate of fire, adjustable trigger and board setup, reasonable efficiency and consistency, etc.
Minis were upgraded to a newer version in 2010 called the Empire Axe which addressed some areas that could be improved.

The Mini design is based from a 2006 marker known as the King Cobra from the Taiwanese company JBS. The Invert Mini is very similar to the Cobra, except for the main support features of the design which have been further developed. For example the electronics are built differently, the design of the body is new, firing assembly size is reduced, and some other changes. The main difference is that the Cobra's air chamber has been relocated to the middle of the Mini's frame, which drastically reduces the body size. This, coupled with a few other major changes, constitutes the Invert Mini.

I personally manufacture several unique accessories and upgrades for Minis and Axes. You can find more information for them on their parent website Nummech.com.

O-ring Diagrams:
I've measured some of the generic seals used in the marker, however many of them aren't standard 1/16" width rings (common in most other markers) so it's difficult to extract the exact size of some. The items listed in the below diagrams with a question mark (?) are sizes I've measured out but am not totally sure of. For some others, I have no idea what size they are (haven't measured). If you have an addition or clarification to these diagrams, let me know and I'll add it.

The tan colored bumper o-ring is the same size as the smaller o-rings located on the front of the bolt guide (I think they're 14.5x1.5-mm ID as noted in the picture).

These are the miscellaneous seals in the marker. A lot of them are 1-mm high metric seals but I don't know the exact dimensions.
