No need to choose.

Why not have both ?!?!?
If I could only have one of the two I would go with the AR-10. I think 30 caliber rifles are just a lot more fun to shoot. But, the ammo is more expensive and heavier.
I trained on an M14 and carried an M16 (in VietNam) and my son has an AR15 today. I chose an AR10 for myself.
Both great guns; I have a passion for .308 Winchester.
The best one is the AR-47! ;)
This is like the noisy debate whether the .270 or the 30-06 is a better round. Owners of either one are very happy, so it doesn’t matter.
If the fecal matter hits the air mover, mobility is an issue. If you have to lug 1000 rounds in a box and run a mile, which caliber would you like to lug?
I don't have an AR-10 (yet). I've got a .308 Winchester bolt action for out to 1,000 yards (but haven't done that yet either).
Ar15 in 6.5 Grendel. Best of both worlds.
I read the title as A-10 vs AR-15, lol.
AR-15s are being used out to 800m in matches, using 69, 77 and 80gr loads. Don’t need a .308 for 400-600m.
“Which results in 800 rounds per minute from this gun,”
Quit misstating that statistic. You couldn’t pull the trigger fast enough to fire that many rounds in 1 minute nor could you change magazines fast enough to do so. That stat. is a measure on the time it takes for the action to cycle. 800 is way too fast and would lead to multiple failure to feeds/jams. Action speeds below 600 are preferred. Magazine springs can only feed rounds upward into the action so fast. At 800 the springs can’t keep up.....
I would like to see a comparison between the AR-10 and the HK-91
First line stopped me. The ArmaLite 15 ( assuming 223/556) is good to 300 or so?
Hmm. Just the other day at a maor High Power rifle match at 600, the top three were: 200-19x, 20018x, and 200-16x.
The first two were shooting optic equipped match rifles in 6 or 6.5 calibers the #3 guy was using an AR-15 A5 service rifle, with a 1-4x optic, in 223 Wylde, 80 grain bullets.
The X ring at 600 is just over 6” ( 2 MOA) and he kept 16 of 20 in that circle, shooting prone, unsupported with a sling.
Tell me again how far the 15 is good for? An 80 at 2750 retains about 1700 fps at 600, for about 500 ft-lbs, the wounding KE value the Army stands by is 300 ft lbs, So the latest AR15 used in matches can indeed be useful to at least 600 yards, not bad for a 22 huh?
Now, all that said, I would prefer the US military step up to a 6mm/6.8 wildcat and run 105s at 2800 from 18inch SPR barrels- that would improve everything- about to 762x51 level and gaining as range increased (over M80).
Oh, and by the way, some long range competitors use the same rifle with 90 grain bullets ( and 6.5 inch twists) to 1000 and do quite well compared to the rest of the field.
