Curious if anyone has run into cycling issues after a trigger upgrade. I have a new M&P10 in 308, put 100 rounds through it without any issues. Installed an Elftmann AR10/308 trigger and have repeatable issues since, honestly I'm lucky to fire 2 rounds before a malfunction. When it fires, it ejects the casing of the round fired without issue and it appears to chamber the next round fine. But when I pull the trigger, nothing, like the safety is on or something. If I pull the charging handle, the unfired round ejects and new round chambers. Pull the trigger and it fires. It malfunctions like this on almost every round, on occasion I'm able to get 2 shots off before the issue reoccurs.
