Here are some update photos of the mechbox (gearbox) cage test fitted to the lower receiver with the upper receiver in place. Bear in mind that I don't have any mounting points complete for the upper receiver to the lower in these pictures, so everything is just in approximate positions.
Here is about where the cage will sit in the lower receiver. Unsurprisingly, it's very top heavy. This location is far enough back for the hop up units to fit between the front of the cage and the rear of the front shroud. The down side of this unavoidable placement is that I'll have to remove the upper receiver to adjust the hop ups.
Tight fit, with no room to play at the front. This has to go as far forward as possible as I still have to make room for the batteries, electronics, and feed mechanism in the space behind.
You can kind of see to nozzles through the frame. This setup puts those nozzles as high as possible to barely line up with the Splaser barrel location without the tops of the mechboxes sticking out of the top of the gun.
It just barely fits under the mid shroud. That's what all the modifications to the front of the cage were about--getting the profile low enough for the shroud to fit. I could not make this fit into the Reach or Halo 4 Splaser designs because they lack the mid shroud.
The mid shroud will be easily removable to allow BB refilling, battery charging/balancing, etc.
Until next time.Redshirt
