You could get an upper or whole rifle in 6.5 Grendel (been tested to be superior to 6.8SPC in close and longer ranges) for about the same price as a regular AR15. While I love the Barrett company and their stance on the 2nd Amendment....some of their merchandise is pricey.
ETA: I myself want one of these....but can't justify $2500 for an AR.

The Grendel doesn't bring anything to the table at typical combat ranges that 6.8 Rem SPC doesn't do as well. Out past 200 or 300 meters, the advantage shifts to the Grendel.
As for the Barret, do they still want upwards of $1200 for just an upper? You can get into 6.8mm a whole lot cheaper (DPMS and others make uppers).
(Parenthetically, I thought the tool bag that hosts future weapons was hitting an all time low with his kinetic energy transfer pepper popper school of terminal ballistics, even though I find the heavier possible AR rounds like 6.8 Rem SPC interesting . . .)

6.8 lacks the ability to shoot a heavy enough bullet. I'm pretty sure the ball ammo they're shooting is 95 grain. Far too light for a .277 diameter bullet.

Actually, the light 6.8 is 110gr, with heavier rounds available. Check out Zak Smith's 6.8SPC FAQ.

Quote from M468 owner's manual
I would assume this is just for the lawyer nannies, right?
Don’t overheat your barrel. Sustained firing of the M468 will rapidly raise the temperature of the barrel to a critical point. Firing 140 rounds, rapidly and continuously, will raise the temperature of the barrel to cookoff point. At this temperature, any live round remaining in the chamber for any reason may detonate (cookoff) in as short a period as 10 seconds.
If the cookoff point is felt to be possible clear your rifle and allow it to cool.
Sustained rate of fire for the M468 rifle is 12-15 rounds per minute. This is the actual rate of fire this rifle can continue to deliver for an indefinite length of time without overheating.
Sustained rate of fire should never be exceeded except under circumstances of extreme urgency.

Yeah, sounds like Lawyer talk to me. There was a very similar statement in the manual of my Bushmaster that I bought recently.

I forgot to mention that it's just a necked down .30remmington (rimless .30-30)

Can you get parts, mags and ammo for it as easy as the AR or what-have-you?
If the answer is no, then it is a range toy, treat as such.

The Barrett is a nice rifle. I would build my own or buy a cheaper upper.
I have built several 6.8's that I was incredibly impressed with. Most people I know that run 6.8's in a SHTF/HD do one or more of the following:
1. Reload. SSA has Lapua quality brass.
2. Have an identical upper in 5.56 to train/practice with.
3. Run a 12" or shorter barrel to take advantage of the 6.8's efficiency.
The main advantage of the 6.8 is the high performance obtained using shorter barrels.
I agree that the 6.5 Grendel would make a better hunting round if that is your major concern. It will also make a better long range cartridge. The Grendel rifles benefit greatly from barrels in the 20-26" range. The 6.8's don't gain much at all from barrels over 16".

There are hardly any other rifles in the world that have the parts, mag, and ammo availability of the standard .223/5.56 AR, are they all range toys?
Right now even rifles such as the FAL, M14/M1A, G3, and AK-47 can't meet that requirement (in this country).

Jesse, do you know how many tens of millions of FALs, G3s and AK47s have been produced?FAL: many domestic manufacturers. Parts widely available. Magazines go for about $8 a pop. Ammo is widely available.
G3: domestic manufacturers. Parts widely available. Magazines go for as low as $1 a pop. Ammo is widely available.
M14: many domestic manufacturers, parts widely available, magazines expensive but available. Ammo is widely available.
AK47: many, many domestic manufacturers (I believe my mother is making AKs now as is everyone else), parts widely available, magazines go for $10 to $15 a pop. Ammo is widely available.
The Barrett is a fine weapon, and the owner of the company is a fine man, but if one is looking for SHTF weaponry, IMHO it is the wrong path.

I know that parts, mags and ammo for all those weapons are very cheap and easy to get and any of them would serve well as a serious weapon, my point was that none of them (from where I'm standing), are as easy to get as standard AR-15 parts, mags, and ammo.
I just thought that making the AR the standard by which availability should be judged sounded a little excessive.

That's why I threw in the "or what-have-you"?

I had a M468 upper for a while when I was writing the 6.8SPC article for SGN last summer. Although we weren't a big fan of the SIR rail, it ran and handled well, and recoiled "flat."
6.8 and 6.5 are specialty rounds for the AR-15 platform. Every AR-15 shooter should have a 5.56 upper for training, practice, and when getting specialty rounds is difficult.
