This guide details an attempt to install an AR-15 trigger into a Derya DY12Y 12-gauge shotgun. The process involves disassembling the shotgun's lower receiver and attempting to fit a CMC AR-15/10 trigger. While the trigger initially appears to fit, live-fire testing reveals significant compatibility issues due to design differences, specifically an oversized Turkish hammer and unique pin retention systems, ultimately demonstrating that AR-15 triggers are not universally compatible with this shotgun model.
