Seems like there is a lot of concerns about us making the wrong M4A1 lately. Think this is a good thing because everyone here is very serious about what we did. As you all understand from our past projects, we usually would put together whatever components we had designed to do a mockup of a vehicle, in this case, a valid small hatch M4A1. That does not mean we are going to release one (small hatch with early boggie) "as is". The M4A1 is nowhere near completion... probably less than a quarter is done; this is why we don't even have a 3D printed prototype yet.
Currently, we are really busy with getting all the Q3 & Q4 releases ready and we just don't have the time to work on the M4A1, that's also one of the reasons why we don't have any updates on the project. Hopefully, this will change soon!
