Hunting AR

Excellent option.
Plenty of ammo options to suit your hunting style 107 to 120 grain bullets.
Initial thought for shooting from a stand or shoot house would be a good quality barrel either 16” or 18”, mid length gas with an adjustable gas block and a free float hand guard.
My 9 YO daughter will be using an 18” barreled Grendel for her first deer hunt in December.
 
Is 223 not allowed? With proper bullet choice
Also if short range 300 blk subs do not kick
It would be better not to hunt with subsonic ammunition. There isn't a soft point around that will expand at that low of velocity. Subs would only be good if you are headshooting pigs. An arrow would be better than subs. Much bigger hole.

There are several expanding 308 sub bullet's out there.
I did say short range.
And if head shots like I prefer doesn't matter.

Subs with a can is a great trainer for short range and then can be loaded with the expensive
Hunting rounds. Not everyone can run a bow well enought to hunt or have conditios that
prevent it.
 
I had thought about the 300 but was not sure of the knockdown since we shoot to about 200 yds.
Forgive my ignorance, but what’s the importance of the adjustable gas block. I’ve seen it mentioned on many threads.
 
My bad 300 blk subs would be a poor choice past 100yd !

The adjustments are to tune your gas system for the load you chose.
To a reasonable degree that can be done with the buffer you use.
Stock buffers are normally light to enable shooting of cheap ammo / less powerfull ammo.
So if you use the more powerful ammo a heavy buffer smoothes things out.
I have shot ar's that were tuned with both and they were awesome.

I run some h2 buffers and like them no agb's on mine yet.

That's the short story, look up the many threads on the subject on sh.
 
I have been using 6.8 SPC lately to shoot deer and it works marvelously. There are way more factory ammo choices for 6.8 and it's generally cheaper, too, if you take the Wolf steel stuff out of the equation.

Regardless of 6.8 or 6.5, yes, a terrific mild recoil deer option.

6.8spc or 6.5 Grendel would be a very good choice.

Grendel is far superior in bullet selection and BC. Keeps energy downrange. Flatter shooting. It's the way to go if she can put the bullet in the right spot. And if you get a good cut rifle, they can be extremely accurate. My Satern bbl.'d 20" does .33MOA regular with the right handloads. Probably my favorite caliber in the AR platform, likely the best all around.

For a hunting rifle I'd try to keep it light though. Flute the barrel maybe. Look at AA, he has a sale going on on his uppers. He's used nothing but the best barrels in the past, not sure what's in 'em now but I'd suspect good ones.

.300BLK is amazing for the shorter ranges and it has basically no recoil either. Grendel is bit snappier than 5.56 but not enough to talk about.

I’m very new to ar’s I’ve been bow only for about 15 years. So what does AA stand for. I’ve been checking out palmetto state
 
At deer hunting ranges 6.8 has more velocity and energy, out to at least 300 yards. 99.9% of hunters couldn't give a rat's butt about how much the BC affects things beyond that. I won't hijack this thread out of respect for the OP, but I recommend the OP make the choice based on real world usage, not theoretical "long range" shots that neither his daughter, nor most of the world, would care about. If the OP doesn't reload, "bullet selection" is meaningless. Factory offerings, of which there are about 3X as many for 6.8 SPC as 6.5 Grendel, are far more useful.

And with a $200 16" or 18" ARP barrel you can shoot 0.5MOA all day long and get maximum velocity out of all factory loadings. No need for a 20" $500 barrel.

And "flatter shooting"? I don't think so. Factory XM68GD or Fusion 90gr are doing almost 3,000 fps out of my 18" ARP. 2750fps from my 12.5". That ain't happening with Grendel.

I'll leave it there, I'm sure plenty will be along to dispute this.

An AR in 6.5 Grendel would have less recoil than a light bolt .243 (I'm assuming it was a pretty light one).
I would however suggest a pretty decent muzzle brake on it for her as it does have a fair bit more recoil than .223
An AR in 6.8 SPC would also be good, but again get a decent muzzle brake on it as it has a fair bit of recoil on it.
 
6.5 or 6.8 both fine choices.
In an ar platform you can tune them with agb and the buffers to be "soft shooters".
A 223 shoots like an air gun when tuned to perfection, still fooling with mine.
