1 MOA or better hunting AR10 build?

[James]

What’s it take to get a 1 MOA or better AR10 with premium factory hunting ammo?

Good barrel and trigger? Anything else that really drives accuracy in this platform?

Due to the looming ban I picked up some Aero precision uppers, lowers, and various parts.

Thinking of building up a lightish weight one in .308 for Rosy elk and blacktail hunting.

16” barrel probably, and hoping for 7.5-8lbs bare rifle, but any advice is welcome.

Not to hard. First is trigger for sure. Factory mil spec triggers are not made to be sub moa triggers. You can do much better but will run 100/150 for middle of the road good trigger. Next is barrel, I really like wilson barrels and black hole have been my go-to on the 15/10 builds. I have others but I can say all of them without a doubt from those 2 are better than MOA for sure.  The rest is just pick and play stuff. I do prefer a good stock with a check piece like the PRS magpul but you pick up a lot of weight. LuthAR and ace make some great lighter options. I also really favor a softer grip with the 10 platform like the ergo grips. Since you get some recoil in your hands on the bigger pills in the 308 and plus.

In my experience, barrel and load are the most important when all other parts and made and installed correctly. Accuracy between a $60 trigger and $200 isn’t measurable if someone buys a poorly made barrel or the ammo doesn’t work well with the setup.

It’s possible to get a weight near your stated goal. You will have to be mindful of all parts that you choose including small small parts that can come in aluminum or titanium instead of steel.  handguards that are mostly made of carbon fiber are one part that can make a big difference in overall weight.

On AR15.com, Molon has a ton of testing various ammo, barrels, etc. with extensive data. Basically it comes down to
Good barrel, good ammo, decent trigger, and a shooter who is capable of 1 MOA.

Easy peazy

Pull up a chair and read awhile, some great information in there

Excellent, thank you guys. Glad to hear there isn’t much more to it than a premium barrel and trigger.

On the hand guard topic, carbon fiber is definitely the plan. The idea of still hunting with an aluminum hand guard in November sounds awful…

I am glad you brought this up, I too need a good comb on my rifles. I was looking at the magpul PRS lite, but even that is 18.5oz I’ll take a look at the LuthAR stuff, but am also open to any other lightweight stocks that have adjustable comb risers.

The Ruger SFAR (Small-Frame Autoloading Rifle) in 308, 16 inch Barrel, at 6.8 pounds, is getting fantastic reviews. By those that have them.

Might be a good example how to keep weight down, and make a good shooter.

I agree
Barrel and ammo
Just like bolt action.
If you look at these AR barrel places ,most will guarantee 1 moa with match ammo.

I bought one of the Geissele G2S for $90 in the christmas sales.  It has brought mine down from like 2.5" to <1" with an 18" barrel, free float handguard, and decent hornady 168 grain ammo.  Dont underestimate the trigger, it makes a big different to my outcomes, even if it was part me to begin with.  I think an 18" barrel is the sweet spot in size/velocity... I don't personally think you need a super premium barrel to get this either, just make sure its a good decent barrel.  The platform is pretty inherently accurate.

Everything I've ever read on the internet states  " Gun will shoot sub MOA , as long as I do my part " .  .
Seriously though the Barrel is the major part . Then the Trigger  .

[bullfisher]

Barrel and matched bolt face, everything else is for you the shooter. I'd recommend a quality adjustable gas block too.
As mentioned above, if your going for a rig that light, weight must be considered for everything you buy. It gets heavy quick and lightweight stuff is spendy...

I have an sig 716 that shoots better than MOA. But after lugging it around the deer woods a time or two it just was awkward and uncomfortable to carry compared to a bolt action rifle. My biggest grip is the rail hand guard and they just don’t sling over your shoulder as well for carry.  Sure will come in handy for other scenarios.

When carrying an AR long distance, safari carry Or Shoulder ready carry position always seems more comfortable. A good adjustable sling is recommended.

Sig 716 is a great shooting 308 AR, but almost nine pounds without optics.

To get to 6 or 7 pounds, in a 308, is an achievement in extreme selective buying. Especially if you include optics.

If you had more time were looking for a complete rifle, I think you’d be in the mood for a POF Rogue.

POF Rogue is a great rifle 

At around $2k, but definitely a quality rifle !
