Thank you everyone for your feedback and ideas. We are heading towards and integrated gearbox and receiver system which will allow many features not possible in a standard configuration. As we currently make gearboxes and receivers, we wanted to integrate the 2 to ensure perfect fit, alignment and allow other features.
So far, the list of features are as follows;
- Lower and upper completely separate. With the take down and pivot pins removed, the whole upper rotates and can separate just like a GBBR or real steal variant. This includes the front guard as part of the upper. Will also suit tappet plates if needed.
- Removable lower gearbox gear access panel to allow easy installation, repairs and shimming.
- Magnetic Tension trigger
- Adjustable spring pre-tensioner to allow +-50FPS adjustment of the main spring
