Black Rifle's roasts are darker than advertised, so if you like medium-dark, I'd probably start with a medium roast. I had their dealer's choice coffee club for a month, and they sent a dark roast (beyond black I think), and it tasted like charcoal to me. Just Black was too dark in my opinion as well. Their light roasts are actually medium. I like Silencer Smooth personally, which is dead-on medium in my opinion. Gunship is good, but the beans are on the oily side of medium. I actually called and asked if I could specify light and medium roasts in that club and was told no, so I switched it to GS and SS. I'm probably going to go to just SS going forward, though.
I honestly avoided trying them for a while because I'd assumed that they were just all marketing, but after hearing the founder on MeatEater, realized that he knows his stuff, so I gave them a shot.
