Had a double fire

[Klem]

And described as a light single stage trigger.... so that would exclude high speed national match.

Fair point.

The majority of Geissele's triggers are two stage however. Even their 3-gun which they call a 'Hybrid rolling lock' is a two stage with springs calibrated to have the first stage seamlessly transition into the second stage. They do have a Single Stage Precision (M4) so it will be interesting to know exactly what it is.

603,
You are certain it is a single stage? Do you have a trigger gauge, or a spring scale that can measure a couple of lbs?
