Got a Delta Team Tactical upper that I assembled on a PSA AR15 lower I built. Using a magwell adapter. It's a Glock mag setup. Running a standard buffer and spring. I believe the BCG is PSA as well.
Have to FTF issues to sort out, but it's super accurate with very minimal recoil. If I can figure out the FTF issues it'll be my new favorite rifle for sure.
