REMINDER! don’t use this kit with out a clear understanding what you are going to do.
you should be very familiar with the FGC-6FA tester data.

the 20UP bolt will heighten the nozzle by a additional +0.10mm making it 0.20mm compared to the standard bolt. making mag insertion on a closed bolt more easy, jet you will most likely offer from a pore air seal comparative speaking.

also you may start to get a poor barrel alinement. that is why there is also a big collection of barrel adapters to play around with. in case you like to fine tune the contact between the nozzle to the barrel. and test what works best.

but understand that this also a easy way of making it not work if you bring the balance out of place to much.

also the current barrel hight is 0, going 0.10 down. or 10, 20,30 UP will mean that the outer barrels are no longer a match with what you are using. unless I might update this after it’s clear one variant is worth making and worth my time spending hours updating all the barrel lineups with jet another option.

and of course the ejector cover is there simply to prevent BB’s from rolling around inside of your upper during a misfeed. making a malfunction clearing faster! but to be clear this only a relevant part in case you don’t use a official BL Upper! as you should know by reading the: how to build a FGC-6BL manual form the starter kit!

also this set includes the FGC-6BL lower to FGC-6FA conversion piece

print settings:
0.2 layer hight should be fine.
you can use the 8 layer walls and a 40% infill.
but personally I moved a bit over to solid prints just to give it more strength in case things go wrong on the field…
