Build question

[Unobogus]

I need to finish my .308 RRA, I have the lower completed. I want this to be a long range target rifle, what length and what twist should I get on my barrel? Also, any suggestions on manufacturer would help.

20 is a common number, twist depends on ammo.
LaRue has a sweet .308 AR that just won an iternational sniper comp. I watched the vid and it blew me away. A 2 man team, with 2 day old rifles, beat 30 ro 40 guys with bolt guns.
Anyway, the have the specs on those guns up, when I build, I am going as close to that standard as I can. Check out Larue Tactical for info
