G&G m4 TR4 CQB-R

2 questions about this specific rif

1. want to know what kind of hop unit I can use with this, the gearbox has had a titan put into it and I changed the motor myself. Any upgrades I can do would be good to know as well.

2. Why are my epm 1 mags not feeding correctly into it? Is it something me (or the tech who’s worked on it) has done internally?

1 it's basically an M4 so any M4 hop unit should work.

2 EPM1, that's why.

1. A plastic ZCI rotary hop with a Maple Leaf Macaron and red nub and a 6.02mm XT barrel from AK2M4 will make a considerable difference.

2. If you want advice on other upgrades, it would be useful to tell us what you want to improve.

Awesome I’ll look into those specific upgrades! 
I was more just asking what kind of changes people made to that rif.

I've not heard good things about them but to be fair, I may be working with out of date info. I believe they were improved at some point.
