Re: AR10 barrel length ?
A barrel length of 20" seems to be the sweet spot for an AR-10 precision rifle.

Re: AR10 barrel length ?
I've seen guys shoot out past 1,000 yards with a 14.5 inch barrel. I have an 18 but would probably go with a 16 when/ if I shoot this barrel out. Get the shortest you think you can get away with.

Re: AR10 barrel length ?
After I decided I was going Noveske, the good people of the hide convinced me to go 18". I thought I wanted a 21" but couldn't find one anywhere. It's handy, portable and, even with the Sandstorm on, not that long. GO 18" and you'll thank everyone who recommended it to ya.

Re: AR10 barrel length ?
What do you want to do with it?
FWIW I have a 16" and it's perfect for what I do with it (backwoods plinking, shooting steel etc).

Re: AR10 barrel length ?
I run an 18.5" and have had great results out to 800 yds. It lessen some weight and makes it a more versatile length weapon IMHO

Re: AR10 barrel length ?
I am conducting an experiment that is outside the box. I am using a 14.5" barrel, on a piston driven AR (the horror)... and it's not even free floating.
What I intended to do was to use a very short platform, and see if I could get acceptable accuracy out of it, to be deployable as a Law Enforcement Precision Rifle.
I am findinig out, that the rifle does everything I ask it to do, with applomb.
With a 14.5" barrel, and a precision rifle compensator, I get an average velocity at the muzzle of 2540 fps with Federal Gold Medal Match 168 Grain SMK.
I have consistently hit 12" steel at 800 yards and in with it, and in real life "deployment" distances... I am able to make T Zone shots with it at 200 to 250 yards and in.
The rifle is more accurate than I am. That's for sure.
The only thing I am worried about, that I have not done yet, is intermediate barrier testing... vehicle windshields, etc...
I would second the masses here. For most practical shooting, I would suggest an 18" AR-10... no more than a 20".
Best of luck with your choices Brother... there are tons of people on here that know their way around an AR-10 platform.
Cheers!

Re: AR10 barrel length ?
I've come to the opinion that the best all-around barrel length for the .308WIN that facilitates decent velocity and portability is in the 16-18 inch range. Like DMack, I am running a POF 14.5" through it's paces, and once I get a few bugs worked out I'm sure it will be a solid 800yd performer.

Re: AR10 barrel length ?
I won't go less than 20" in my three .308 ARMALITE
AR-10s.
One is a classic 24" 10T that will probably become
a 24" Bartlein 6.5 Creedmoor within the next six
months topped off with the SH Group Buy SS 5-20x50.
The 20" 10A4 has less than 40rds through
it and my brother shot 5/8" and 7/8" groups when
July showed up. The 20" 10T is virgin. Still
deciding on a LT-158 or NF Unimount for the NF 5.5-22x50
that's been laying around since May or June.
I would accept a Bartlein 18" with a can if I ever get
into tactical competition.
Yeah, I know. No help from this guy.

Re: AR10 barrel length ?
Ive got the 26" floating Bull on my RRA. I had 2 1/2" groups today at 500 yards. Im shooting my handloads. 168 grain sierra BTHP 46 grains of Varget. can easily push it out past 1000 yds, but its a heavy weight....dont plan on carrying it for much distance.

Re: AR10 barrel length ?
20" here, but could be talked into a 21" or even an 18" next time. Mine goes from house to range and back. Not carrying it for hunting or alike. If I were, I'd opt for 16"-18". Don't just look at length, look at profile/diameter as well as balance. All those factors come into play when deciding on a build or new barrel for your existing.

Re: AR10 barrel length ?
Hawk is right! I would likely stick with my 18.5" barrel but would not keep a bull barrel next time. The tactical bolt gun shooter got the best of me on that part of my build

Re: AR10 barrel length ?
I just built a 26" barrel 6X47 Lapua with an extended gas system (2"). Cycles very smoothly but I haven't had a chance to get it on paper yet.

Re: AR10 barrel length ?
For mostly precision work, I would go 18" If I was gonna also do a little run and gun with it I might go 16"...

Re: AR10 barrel length ?
Another vote for a mid weight contoured, 18 inch tube on a .308 gas gun. Mine has been to 1000 yards, though some optics mount in 20 MOA flavor will be benificial if not necessary.

Re: AR10 barrel length ?
18" Noveske Does the Job for me I can launch 190's at 2600 and 150's at 3000FPS...CAN shift is 1.5MOA 6 oclock every time...Pounds steel at 600 yards in .5-.7 MOA ...Kills things DRT...
Its a heavy weapon,add Scopes Lights Bipods Any extra Items you may need and we are 14lbs easy...A light barrel around 16" would be nice and shed me a pound or so,But I know CAN shift will increase heat may effect accuracy sooner,But Honeslty I dont do rapid shoots with this weapon 3-4 rounds is average Per session and 600 yards max.If I didnt have the CAN or didnt need the CAN on there I would Go 16" Light contour for me,I have other weapons system's for Long range.My Noveke MA-10 is more than up to the task on 1k Duty,But its set up diffrently..

Re: AR10 barrel length ?
I have a 16.5 and have hit 1K, but it wasn't easy to get there. It's consistantly spot on 8" steel @ 600M. I am just beginning to play with 178 AMAX to see what it will do further out.

Re: AR10 barrel length ?
Nice Rifle! What twist barrel are ytou running? My Rock 1:11.27 and Tikka 1:11 do not seem to like the 178 A max but both love the 168 A Max and 175 SMK's

Re: AR10 barrel length ?
@ Branson, thanks. 16.5” heavy contour, fluted, 1:10 twist from Rock Creek. I'll try the 168 AMAX. It does seem to like Hornady 168 BTHP out to 600M and change. After that its a terd with the ammo I have used to date. Someone else suggested TSX 168. Made some at 39grs of H4895 for a starting load, and waiting to try them out.

Re: AR10 barrel length ?
I just got a 21in Noveske N6, but I'm probably gonna end up getting it cut back to 18 and thinking about having it fluted. I seriously doubt I'll ever shoot out to 1k - No ranges anywhere near me that are that far. It'll just make it a tad bit lighter and little more maneuverable.
Personally I'd say go either 16 or 18 in.

That is impressive velocity with a 14.5" tube...
What type of barrel is that?
