Can someone give me the scoop on these guns relating to a few questions; What changes were made to them from the original design as a result of the lawsuit? Are the original ones better or more similar to the HK weapons?? Also, I have seen videos of GSG-5's with what look like original HK Navy lowers on them. Are these guns interchangable to some extent with HK lowers??? I am looking to get a pistol model soon, and I want to research these questions first.
Thank you
Look at the sticky threads above to answer your questions regarding modifications.
