yes however no reload and inf ammo are the only problems i have that wont work but i really dont care about them but yes you are right about the gmp thingEverything does work in the trainer, HOWEVER if you use the infinite GMP it'll cap it at an amount that is less than what some blueprints need. If you just do event FOB missions and play the game you'll get to the actual cap that includes the online GMP and client side GMP amounts.
