My first build has always suffered form inconsistent performance. As Rick is well aware we did a lot of back and forth on what the issue may be in the last two years. I did a couple of re-dos on the dis-connectors and still had to many issues with the cycling and reset on the trigger. I decided to try one of the new booster units that became available. This has done the trick! Did 112 rounds with out missing a beat last time to the range. If you are having any cycling issues I suggest giving one a try.
