aekdbbop 9mm AR In semi mode, the hammer is releasing after the bolt cycles and (after putting constant pressure on the trigger) then results in a dead trigger. So the trigger isn’t resetting correctly. It is dropping the hammer instead. Any help?
hoffmantactical Have you run a full test on the FCG with the upper off? Is ejection working fine? Short stroking is unlikely with a blow back, so probably an issue with the disconnector or hammer.
