This is a true split gearbox meaning the top part that houses the piston and spring is one complete unit that can be removed from the lower once the rear receiver pin is removed. This enables easy servicing of the gearbox.
World class aerospace grade CNC 7075 aluminum. Currently only available in Silver.
These split gearboxes do not support a tappet plate (old school tech). You can use these gearboxes are to suit the Aztech APACHE tappet less cylinder head or a HPA engine
This gearbox housing is a straight swap upgrade for an APS gearbox plus most other receivers with minor adjustments to the receiver. All the original parts can be transplanted into this gearbox housing upgrade optional at this point.
CNC finish may vary per item, being 100% custom made from 7075 aluminium, these are raw finish with CNC swirls, wire wheel and buff marks for smooth touch finish of the incredibly hard to machine 7075, the surface finish is not intended to be pretty, it is built for performance. In this case they are 100% function over form, we have not cut any corners in design.
