I've been seeing the discussion in the 007 new direction thread and the comments regarding the restricted uppers versus lower recievers (Mp5 and UMG).
I'm thinking of replacing some of the body on my G36. Is the upper reciever restricted for G36s? Which part is restricted? (obviously not B, the magwell). The lower reciever of the G36 resembles the Mp5. Why is the grip/trigger not restricted on the Mp5?
vs.
