[ARCHIVED THREAD] - Help with trigger not resetting

Posted: 1/23/2013 2:49:00 PM EDT

I have a 9mm sbr with a rock river lower with a hahn block. It has a two stage trigger and I had the bolt ramped by ADCO. I am also using a Slash 9Q-T buffer with the wolf spring as I am running a AAC Ti-Rant on a 7" barrel. I went to the range for my first shoot and after every round I had to rack the bolt to reset the trigger. I was using American Eagle 147 grain and also some 147 grain reloads that all chrono'd between 950 and 1030 fps. The first round would fire and the next round would load but the trigger would not reset. If I racked the live round it would reset the trigger and the next round would fire but then I had the same problem. Am I thinking right about maybe trying a lighter buffer or spring as it seems like my bolt must not be traveling far enough or am I overlooking something?

Try a standard buffer spring and make sure your hammer has a smooth face
not a hammer with a notch cut as they sometimes don't work well with a ramped bolt.

That 2-stage trigger may be the culprit. Which 2-stage is it?

It's a Rock River 2-stage

Old style with the notched hammer or the newer RR smooth face hammer ?

It's one of the newer solid round face hammers, there's no notch.
