1 of the interesting things I experienced building this, was the huge difference in quality of stripped lower receivers. A couple of years ago I completed my first stripped lower AR build with a CMMG lower and DPMS Lower Parts kit. The build went together like butter. This time I had a JD Machine stripped lower and RRA lower parts kit. These parts didn’t fit together as well as my previous build (i.e. receiver pins do not slide out smoothly, trigger guard pin holes slightly off) not sure whether it’s the lower or lpk or both to blame.
Due to this being a piston based upper. I had to Dremel tech Magpul – MOE Hand guard to accept the wider diameter drive rod.
