Joined up to get some ideas on barrels to finish up a Aero M5 build. I was trying to decide between going with JP or Rainier when I stumbled onto Black hole. Getting a custom barrel locally has a lot of appeal. Leaning toward a 18" Semi Bull, .308 barrel. Anyone know the weight difference between the straight and honeycomb fluting?
Just to follow up on this. I ended up ordering a 18" rifle length barrel with the honeycomb fluting. It's a shooter. I need a better range, bench, bags, etc. But even just shooting off my bipod, its MOA or better with factory match amo. I couldn't be happier.
