I built mine from parts I trust. DD LW barrel factory pinned lpgb under Centurion mlok guard. Aero upper, tool craft bcg. Aero lower with A5 and bcm stock. Mil spec trigger running surefeeds and pmags.
From the first round, never a hiccup. 6.5# loaded (20rd). A factory pinned lpgb is pretty ideal for reliability.
