Yes, AM and TM have pretty good bubble lenses - none of them are as good as flat lenses but if you buy a good kit from a good source chances are you'll be okay, and if not you can always swap them out.
Do you have a CNC or laser cutter? You could just get some 1/4" plex and cut out a new one.
Barring that, I would try searching for Sterling triggers as that what an E-11 is based off of, or model your own and share it for everyone here.
Watched the first few episodes, not a fan so far.
That said... that gold stormtrooper! That almost makes up for the show being such a snoozefest. Anyone know where I can get my FOTK kit goldplated?
Rat is correct, interior strapping is not covered by the CRL.
FYI, it is possible to set snaps using split rivets, here is my armor and the riveted side is detachable:
I have this one: https://www.amazon.com/Anker-PowerCore-Lipstick-Sized-Generation-Batteries/dp/B005X1Y7I2
The only thing I don't like is that the power button is hard to reach with it mounted to the helmet, they make a 5000mAh one with the button on the side that is a bit bulkier but may be a better bet.
I have seen people sew their gaskets to the undersuit to save time kitting up, it is doable but as I still don't have my FOTK yet (thanks, Anovos) I can't comment on which system is "better".
