“The installation of the nickel boron two stage trigger was straight forward and fit very well. The performance was exactly what I had hoped for. The initial trigger pull is very smooth until your finger hits the "second stage". When the second stage is encountered the trigger "breaks" very crisp. This helped reduce the shot group size from 2" to approx 1" at 100 yds. I was using surplus military ammo, I'm sure higher quality ammo would reduce shot group even more. I am very pleased with quality and price!”
