Recommended barrels for new build

[gregor]

I went ahead last night and ordered a PF 20" Lothar Walther barrel with a target crown. I didn't think I would need a brake of any kind on it. I am mating it to a Vltor MUR upper to get a thicker, stiffer upper for it. I already have a Bushmaster lower it will attach to. I am also planning on getting a 15" Diamond head free float handguard. I have one on my 300 BO and love the they feel. I already have an AR Gold trigger in my 223 that I might pull out and use, but haven't decided for sure. I know you are thinking to just the grendel upper on it but the lower is a cheap Delton lower, plus I think the Bushmaster lower would be better. I went ahead and got the BCG from PF also in a rifle length gas system. I will eventually build a dedicated lower for it. What are your thoughts on the 20" LW barrel? The reason I awent with the 20" barrel is for hunting and bench work. Might even change it to a 22". Any thoughts on that?
