Want to build a "precision" ar-10, where to start?

So, I have built my own ar-15 before came out awesome. Decided I would like to get into long distance shooting, so the 308 was my choice. I was thinking either a remington 700, or an AR-10 built from lower or commercial (if possible?) and upgrade.

What are some good quality brands? What should I be looking to upgrade to get more bang for the buck in accuracy? I was thinking 20" barrel.

My budget would be in the 4K range with a x24 scope.
 
AR15's are easy to build, 99% of the parts are interchangeable, the same can't be said for an AR in 308. There's different uppers and lowers and bolts from one manufacturer to another.

Personally I'd just buy a complete rifle, KAC or Patriot Ordinance Factory would be my first choices if money wasn't an issue.
 
Check out Rainier Arms website, Canadian Tactical Cowboy Supplies (a sponsor here) has an import deal with them, so you can get a bunch of stuff from them.

Aero Precision (or MEGA, or DRD, or Rainier Arms in-house brand ones) are all really nice upper and lower set in the DPMS pattern upper/lower (which is the more available than the Armalite pattern upper/lower), then a nice free float handguard and a barrel. Rainier has their "Ultramatch" SS barrels, which are quite pricey but worth it. Shilen barrel blanks. Then most of the other components are just AR15 parts. You'll need a DPMS style gas block and gas tube, as well as bolt carrier and charging handle, then pretty much all the rest are Ar15 components.

A REM 700 5R or better for starters.

No Barbie gun is ever going to equal the performance of a bolt gun at distance.

Now if you mean lob a bunch of factory rounds 300M and call that long distance shooting then maybe...

Go the DPMS compatible route over the AR-10 route if you want the most options of compatible parts and a 24 inch heavy barrel min.
 
I am biased on saying there is a Modern Hunter on the ee that is well worth a look, but it will hold its value imensely over an AR10 due to its Non-Restricted status.

Its nice not having to have additional paperwork and very tight storage and transport laws to not have to follow, as well as I would always rather be able to shoot out on the farm or crown land at will.

OP,
What do you consider long range? Do you have access to a range with lanes longer than 400m? Otherwise, consider where you will be shooting. Remember AR variants are range only toys for the time being. The modern Hunter is NR and can be taken to the back country for true long range shooting.

Great besides the fact that it is not particularly accurate.

I'm a huge 308 ar fan, and have owned many.
If you're really looking to shoot accurately past 600 yards, there are few that fit the bill. The LMT mws (ss barrel), les baer, larue, or gap-10 are about it. All are expensive. All restricted.
Do yourself a favour and opt for a tikka varmint, or rem 700 5r, toss it in a chassis, and go shooting. Spend the saved money on reloading stuff. You'll learn more and be a whole lot less frustrated. Shooting a gas gun for accuracy is harder than a bolt gun, and they're not as consistent in their accuracy. That's a fact.
Long range shooting is all about consistency of shooting form and accumulation of data with a reliably 1/2 moa rifle.
I have had many 308 ar's that could should 1/2 moa groups. None of them could do it reliably.
 
I agree with all the member choices, one was not mentionned but it deserve to be considered, with a tailored handload ( 167 gr Lapua Scenar) my Armalite AR-10T is a sub MOA rifle...
The AR-10T/S&B PMll combo is a very accurate rig, a keeper... JP.

The range that I would be going on "regular" basis is capped at 300 yards. I do not hunt or anything like that so the NR status isn't really that high on my list of priorities (I shoot more handguns anyways).
 
If it's for range only and max 300M then I'd be inclined to go for something like an Armalite AR-10/10T or similar with a nice stainless barrel. I'd think building a 308 AR would be a painful experience due to the closed nature of a lot of the parts (unlike AR15 which is pretty much an open platform). Then put a nice scope on it with the remainder of the budget (Sughtron, NF or similar, but longer than 24 think Sightron 10-50 ;) - unless you have a good spotting scope).

I picked up a Wyndham SRC308 last year on sale for around 1400 iirc and it's really not bad for that kind of distance. With a good load I can get 1-1.5 moa groupings of a bench with a bipod and bag. No comparison to either of my bolt guns, but not too shabby. Pretty sure the load has a lot to do with it, as I couldn't get anywhere near that with factory ammo. I've toyed with the idea of replacing the barrel on the Wyndham (the rest of the gun is good quality), but other things have been distracting me and I haven't done anything about it yet.
