Absolutely fill us in. I have a 14.5" 2.0 and it's gassed on the light side. I'd probably be a buyer for a 12.5 middy. BRT tibes work. I have a couple, but wait and see if you need it. I'm guessing you won't. Finally, can... I'd probably start with a .30. I went .556 and now have to buy a .30. You might think you don't need a .30, but things like 300bo sneak up on you and then you're left with a 5.56 can that's not going to work. Just my thoughts. Something like the griffin exprror in .30 would be reasonably light and give you options down the road.
