Yondering, I'm helping a friend who's building it for me. He's put together at least 15 standard AR's from the ground up. Hoping any issues that arise we'll be able to work out.

Anyone worked with a Gibbz Arms receiver before?
Aslo looking at doing this in 223 Wylde; thoughts a bbl maker that chambers in this and what profile would be best for something that's going to get carried a lot?

All help is really appreciated!
