So my buddy who has more money than skills (had to teach him how to break down his own rifle) asked me to do his EBR swap for his Socom 16. So being the good friend I said I would do it. Other than the piston guide it was pretty straight forward. It was my first build of an EBR so it took me almost a hour and a 1/2 to swap out the piston guide. Also he had a scope mount that I had to cut down and paint to work with the EBR stock. What do you all think?
