I finally received all of my parts for my GBBR project yesterday and spent the entire day building it. Its finally done!
I didn't take any pictures of the packages or the process of the build, i got too excited. lol But anyways here's the final product!
Pics of the internals: (all G&P

A close up shot of the receiver
I had a bit of a problem with the forward release. It was contacting the pin that held it in place which caused it to jam in the forward position and started rubbing against the BCG. Fixed it with the help of a file.
I still need to get a CQB length inner barrel. :P
