Really looking for a Rock Creek Or Hawk Hill barrel from a company that's ready to go for a AR10 I'm buidling. I know there are some companies that do this but can't find the file I had saved with their names.
Add Lilja to list. Two I have-6.5CR/6.5 Grendel- from off the shelf, shoot right behind two Bartlein’s in same calibers. If you have a choice, get one with a JP extension and a decent feed cone, if you want to assure reliable feeding.
A great choice. Also, another good choice is for you to pick your chassis and have your barrel made by CLE. Also MSTN and GAP makes guns from scratch with those barrels
Email Frank. I did. He can spin you one from a Douglas for 6.5cm. Known him for about 25 years and his barrels and rifles I have had have always shot superbly.
