Which AR-10 is most accurate?

Mine.

20" AR-10A4 for best bang for the buck. I have posted that I have never seen one NOT shoot less than 1" @ 100yds 5shot groups
with fodder that it liked.

I would say sub-0.75" has been the norm for me having gone through 4 or 5 of them since 1999.
My latest A4 likes BH 168gr NBT. Never had one like it before... Hornady Custom 150gr SST has
always been majic in all of them.

I also have a 24" T and 20" T. Best Bang - 20" A4... and the Ts are lasers.

I have several Armalite AR 10s and they are great. I also have a Rock River LAR 8 Standard Operator wich is just as accurate as any of my AR 10s, The RR is fantastic except it weighs 10.4 Lbs which is heavy as hell for a 20" gun. Fun to shoot but I would not like to hump it around all day.

But if I run out of ammo is a SHTF sit I will have a monster club to swing. I may see if Rock River has a set of training wheels for it. Easier to carry around

Here is an upper for him that meets your description. ZERO rounds.

APPLE HEAD!!!

Armalite guarantees their accuracy, and they put out very accurate rifles

Let me guess, you've never even touched one but you're going to give us your expert opinion on them?

The Mag relase is nothing like the FAL's, it is identical to an AR but improved in that it is ambi. It also has the finger operated bolt catch/release which is a big plus not found on other "AR-10s".

Let's get back on topic please.

He never asked for an expert to opine did he? He asked for opinoins and he got mine. You don't have to be an "expert" to see all of the problems with the earlier rifle by Bushmaster. I remember that and I would not drop my hard earned money one. I looked at one in a gun shop and I didn't remember seeing a traditional AR mag release, so my bad on that one. My expert opinoin on the mags stand as well.

I did'nt know you had to be an expert to opine around here and I certainly didn't know I need your permission to post....

About a week ago i was in your same shoes.. debating over the Armalite AR-10 and the RRA LAR 8. I ended up with the new Armalite AR10 A.
Love that it takes the old mags and the Magpul PMAG 308 (lot less expensive)
Found a local dealer with one in stock and got an great deal on it too.

WHAT A SHOWOFF!

But I WANT that accuracy.

heggissvi, I have a question, I often see groups like this posted on articles showing accuracy, and it is a good group. But why not in the black ? Isn't the goal to hit the center of the target? I've never asked but maybe you can tell me why.

Yup was aiming for the black. This was my first time shooting that far, 550yd is the max distance I normally get to shoot to. I was testing 175gr SMK grouping for shorter distances when got the opportunity to go shoot to the military range. So I had my gun sighted in at 220yd and not actually sure what speeds the bullets were leaving the barrel. Sure I'd chronoed them but don't trust chrono that much, and as we can see, it was hitting little low. I've now adjusted my table for the correct speed and now should hit the center. From 220yd to 890yd had to adjust 188 clicks up, but was only 184 because of the old chart. The reason group is little left is wind, we had a calmer moment in the wind so decided to take the shots to a papertarget (shot metal rest of the time) and didn't take away any windcorrection.

Yes that is a "lucky" group, usually the gun runs about 1moa (with 20 shots), but still was surprised for that distance. Oh well tomorrow shooting to 1100yd, we'll see what happens when those bullets fall subsonic

Also ppl might shoot multiple groups to a single target so you can find the groups all around the target.
