It’s relatively heavy and feels solid. 750g dry.
Shell is white nylon painted/sprayed with a rubbery finish. Nice feel but will probably scuff.
It’s surprisingly quiet and it is rear heavy, even before you extend the weighty buttstock. Extend and you will need to work to stop the barrel pointing skywards.
A metal outer barrel plus flash hider will certainly help.
Trigger.
There is nearly an inch of play before the trigger offers any resistance.
Safety.
Difficult to access especially since it locks the trigger so far forward that it is hard to reach in to take the safety off.
Because of the excess play however, it is possible to pull the trigger way back and then engage the safety. It’s stupid but if you do that, the trigger is locked 75-80% of the way back (to where it should be) and you can then use it like any other blaster.
Unintended practicality. 
- Spring is 1.1mm x 8cm x 10mm
- Piston has weak seal with 6 x 1.5mm holes.
- Cylinder head seal is good.
- Barrel is not secured. 7.4mm x 15.7cm
- Nozzle is glued.
- Mag holds about 40.
- Battery compartment is short but wide.
Will it all fit in an LA2019 @Arty_Marty? Yes.
Does it all look familiar? Yes.
This closely resembles a 3DG G17 gearbox in layout and parts.
Similar tpiece and tappet.
The 3DG metal gear upgrade may even fit. That can wait.
Anyway, having a loose barrel and weak piston seal but average 180fps is encouraging. 
What’s next?
Apart from the seals and gluing the barrel, a comparison with some spare 3DG gear sets and some general tidying before some work with the trigger, a 10A switch, rewiring, motor change and an outer barrel with the right thread.
