Then, if you want a 200 yd or less caliber with more potential, get the 300 blackout. I have pretty much ditched 5.56 for 300 although ammo is scarce. 300 Blk is a do-it-all caliber including suppressed options, short barreled/pistol options and all parts comparability with 5.56 except the barrel.

If you want punch at a long distance, the 6.5 Grendel is unmatched in the standard AR platform. 1000 yard hits are very possible along with much more energy at close ranges. I have a stripped lower begging for one of these but there are just aren't any available.

6.8 is a fail in my opinion. It hits harder than the 300 Blk and has more range but it is expensive and the 6.5 Grendel outshines it in almost all areas of performance.

The big bores are for serious medium to short range hunters.

There is my 2c! Now back to loading more 300 Blk!
I added a 6.8 for deer hunting with an AR 15, Hornady Custom ammo for my 6.8 is about the same as for my 308. Do I plink with 6.8? No, I use my 5.56 and steel case ammo for plinking.

If/when I start reloading, I can load for both my 6.8 and my 270.

It is up to the OP to decide, 6.5, 6.8, 300 blk, they are all good rounds.

There are also the 243 WSSM - 25 WSSM - 30 OSSM caliber uppers from Olympic Arms.
Olympic had a bad rep several years ago,but I know some guys that have these WSSM caliber uppers,and they function well/shoot well,and the ballistics blow away the others like the 6.8 and the 300.

Ammo for the 243/25 WSSM is pretty common at most big dealers,I'm not sure about the 30 OSSM.
If your wanting to be able to hunt bigger game,these will give you a lot more range than most of the others.

Always 5.56 first! It is an amazingly versatile cartridge. In general, if you don't know what you want, then wait...

300Blk is very interesting, but not as a first rifle. Is this your first?

I agree your first AR15 should be a 5.56. You can add a .300 or other upper later. The lower is the only part that has to be purchased through an FFL.

you only need one lower. the uppers for all these calibers can be used with just one lower

I have shot a 223, 6.8, 6.5 grendel, and the 50 beowulf all of them are great calibers. The 6.5 and 6.8 are not that different. The 6.5 is a little faster but uses a slightly smaller bullet. The 6.5 is supposed to have one of the best balistic coeficient however all can be extremely accurate. Either of the two would be great choices. Then there is my favorite the 50 beowulf. The 50 beowulf shoots a 50 cal bullet typically between 300 and 500 grns. The recoil is not horrible and it is very fun to shoot. The 50 beowulf will stop anything within 250 easily and would be great for shooting pigs.

Below is a 50 beowulf cwrtridge and a 556

223 will do fine, if you load it with Nosler 60 gr Partition softpoints, for deep penetration. Need 1 in 9" rifling to stabilize them, tho. then you can switch to .22lr in 20 seconds of parts swap. google for Ciener's $200 /22lr conversion units. I've heard that 1 in 7" rifling can cause problems with accuracy and the .22 unit. dunno myself. gotta have sense enough to not aim at the shoulder blade, tho, and not shoot at the north end of a south facing animal. be sure to get a NM, 2 stage, drop in trigger job parts set, from RRA, rock river arms. you won't believe the difference it makes, iin accuracy and speed of hitting. $150 or less.
