Thanks.
I still have some work to do.
I have a gas block with built in flip up sight for the black gun and a flip up rear sight to go on it.
I have some rail covers on the way as well.
I want to do some more work on the gearboxes and put Mosfets in to them to allow higher voltage and up the ROF.
I want to put tighter barrels in as well.
The black gun houses it's batteries in the stock, it takes an 860 mah Lipo perfectly in the Stock tube.
The other one houses a 1600 mah Lipo in the handguard.
