Misfired rounds - Rise Armament OPMOD Hex-C AR-15/AR-10 Enhanced Rifle Trigger

First, looks quality, feels solid, installed in 5 min. Seemed unresponsive at times in dry firing. Would pull, it clicked, then 1 sec and hammer strike. Thought my safety wasnt in correct. Took to range. Fired two dif. 300BLK out mftr rounds. Second round was a misfire about 7 times. Primer was dented. No ignition. "unnerving". Looked it over for mistakes in install. Took to expert gunsmith. Didnt go into what I experienced just said misfire/two amos. since it was a new AR build. He suspected head space was loose. He called next day and said it's the trigger. Nothing with barrel, bolt, fire pin, safety, external springs but internally, it has bad tolerances/bad springs or all above inside the Rise Armament casing. Maybe it is one in 10,000. ?? Had to return. O Planet is gracious as always and just awesome.
