Ok so its not the end of the world, but I ordered some parts from Mississipi auto arms. Long story short, my tromix galil handguard doesn't fit (and I didn't do the best job trying to make it fit) and my agp 10 rounder doesnt lock into the gun. I understand sometimes some minor alterations are needed and I sent email to tromix about the handguard. However, Im not sure whats up with the magazine. What do you guys think?
