Yep, like TJohn said, it only affects some. To make that funky 308 stock trigger work, I believe they modified the 308 safety a bit. My 308 was an older 22 inch so that's why I brought up the safety check issue. Brian said my safety was way shorter than any one he had seen and added material to it. Perfect job he did. I also had him notch the safety to use as a bolt-hold open and I believe he added material to the trigger to compensate for not putting the original bolt hold open back in:
