I have an SLR-104UR 5.45x39, SBRed and now I want to install a binary trigger on it.  

Looking at Franklin Armory and Fostech, and saw a video that showed that BFS outran the SAM7 SBR bolt, but also heard that Echo has a terrible trigger pull feel...

so, I decided to check with the hive... anyone runs them?  any issues with Krink timing or rate of fire?  any mods required to install?  what is the preference?

thanks in advance
