I suspect that they realised that it just would not work very well.
The gun itself actually worked very well, and was quite interesting to shoot.
Unfortunately by the time we got it to be production ready the paintball market had changed drastically and at the price point we were aiming for the company didn't believe we could sell the numbers we needed to justify and cover the costs of going into production.
The cash required to launch production compared to the risk level just meant that the appeal was lost. So the project was put on hold. Indefinitely. This was just as NPS and PMI were being merged so all numbers and financial outlays were under heavy scrutiny. It was decided the money was better spend elsewhere.
The gun wasn't really designed for the UK type market. It was more intended for the backwoods ball and renegade style play that is so common in the USA, and where it's harder for people to get gas fills.
