I did the HB trigger spring kit last week. About half the pull weight is great. The install took a long time compared to an AR upgrade. A lot more steps. But the videos make the operation clear. The biggest lesson learned is to file a groove in the end of the stick/rod used to hold the spring down during re-assembly. It’s a cuss-invoking 3-hand operation.
The HB Theta extended charging handle is an even more appreciated upgrade IMO. The extra finger pulling that heavy spring makes all the difference.
