Drop-in Adjustable Trigger Assembly with Camming Safety Linkage

摘要

A drop-in adjustable trigger assembly has a camming safety linkage to selectively move and engage a bolt sear to positively prevent movement of the bolt sear. The drop-in trigger assembly housing carries a pivoting bolt sear engagement member which is connected to a sear safety linkage. The housing has a sear safety linkage slot defined therein which guides the pivoting sear safety linkage in response to actuation of an upwardly projecting thumb safety lever's actuation. A trigger bracket preferably carries a removable, reversible trigger shoe and is configured to pivot within the housing about a pivot point within the housing, and the trigger bracket carries an adjustable rocker having (preferably) a first stage movement adjustment and a second stage length adjustment. The pivoting safety mechanism's safety linkage pivots rearwardly to push upon or cam the bolt sear upwardly, thus disengaging the bolt sear from the trigger sear.
