I'm trying to make my G&P XM177E2 as best as it can be from parts I have.
The E&C gearbox has a gate Aster installed already, I've shimmed it myself and has incredible consistency on the airseal (so much so, the site chrono-er commented on it).
The G&P gearbox is untouched from whenever it was made years ago.
My questions are:
Can (or should) I just drop the E&C gearbox straight into my XM177E2 body?
If I should swap some parts around, what ones? I noticed the nozzle on the G&P is metal. I don't have calipers to measure unfortunately.
If everything is better on the G&P, will I have to cut anything away to fit the Aster? I have minimal tools as I've just moved to where I am and couldn't bring anything with me.
I also have a ZCI rotary hop left over from a previous build, should I replace the G&P metal one? The dial is very stiff.
Any help greatly appreciated.
