6.5 barrel questions

[850guns]

So I'm looking to build a rifle in 6.5 Creedmoor.
And I know nothing about the caliber.
Who makes a good barrel?
Length?
Twist?
Gas system?
Buffer system?
Does it use a .308 bolt?
I'd rather build, as I have a receiver set.
But I'm open to purchasing a complete upper if it's a better option.

And later I'd like scope recommendations.

-Bartlein or Kreiger make excellent barrels.
-I wouldn’t go shorter than 22”. Or 26” for speed. You will gain 12-16fps per inch of barrel
-1-8” twist for 130-144 grain bullets.
-rifle or longer gas
-rifle length butt kit or JP silent capture have worked for me
-yes standard .480” case head.

I'll throw my $0.02 in. the Bbl length , GB O.D. even having the muzzle threaded ALL depend on what you want to do with your rifle.
And to scopes, again , depends on what you want to use your rifle for, your age ie; eye site.
My 308 AR with a 26" Bbl.and with a 10x40x56 scope hit the scales at 23 (+-) Lbs. The groups were shot at 300 yds.
