I would like to know who people feel are the top five manufacturers for barrels in Grendel are. Also, who might sell their barrel with a headspaced bolt? Recommended bolt carriers for this AR15 project wil be helpful. Twist rate? I think I would like to shoot towards the heavier end of the 6.5 bullets but I want to be able to shoot 123's as well. Rifle or mid length gas port and what size should the port be for each length. I can always buy a blank, profile it and get a reamer from PTG, but I'd like to see what's available off the shelf and in STOCK! Thanks in advance for any help you send my way, Steve
