    On both trigger assemblies that I purchased when trying to fire them the trigger would catch after bolt returns from the rear and would become a dead trigger, I would have to force the trigger forward to reset and fire the next round or I would have to slap the rifle each time. Finally got tired of it pulled them out and installed two drop in trigger assemblies which worked perfectly.
