Got a new drop in trigger for the wife's 300 Blackout and got a surprise. This absolutely wonderful crisp breaking trigger of less than 4lbs delivered a surprise. It started firing 2-3 round bursts. Everything was absolutely stock in the fire control group and I dropped in this $160.00 wonder she purchased new at the local gun show. I thought I was going to get arrested at the local range as I heard comments "He's firing full automatic"
