Barrel selection

[Cfont003]

Hello, I am looking to build an ar15 chambered in 6mm arc and around 20", my goal is to make the firearm as accurate as possible (preferably sub 3/4 moa) while making it as light as I reasonably can. I was looking at proof research, Rainer arms, and ballistic advantage. I'm open to any companies.

Compass Lake Engineering, go fluted to save weight. They have Bartlein, Douglas and Criterion blanks. These are $400 to $800+ barrels.

Compass Lake Engineering Bartlein or Proof Research. I've had both in stainless and have no complaints.

About how much does a fluted 20" Bartlein barrel weight and about what can I expect accuracy wise in an ar15 platform with handloads?

T-Box makes an ARC. I have one in a 6.5G, 130gr bergers typically shoot 0.66 or less.

Can't tell you on weight. My bull (.936 gas block) 24" ARC Bartlein from CLE puts 20 shot groups in the .8-.9 MOA range.

craddock precision is definetely someone to look at. Quality barrels. Good company. i have seen proof carbon fiber barrels somewhere, but those would give you the lightest weight.
