First of all, I want to thank everyone who has posted a resource of any sort here on M4C. By searching and reading, the answer to every conceivable question that I had during my build process was already posted and in most cases well documented in advance.
I also want to thank Bravo Company USA for their outstanding selection, pricing and after-sales customer service. Paul went out of his way twice to exchange things for me even though I had skated across the 30-day exchange window. Sometimes it’s rough buying parts in advance of other parts, only to find out later that the combination doesn’t work together the way you had hoped. He had mercy on me and let me exchange two NIB components without worries. 
That being said, here she is. I’ve owned a few AR15 rifles in the past and modified them all, but this is my first ever build from a bare receiver. It was incredibly simple and LOTS of fun.

Tax stamp arrived! 
Here is my SBR project, based loosely off of the US Navy MK18 close quarters battle rifle. All furniture is Magpul in Dark Flat Earth.
