I'm not buying an AR until one is chambered in 7.62x54r.

LOL, just re-chamber an AR-10 is what I am thinking!!!
I like the 300 BLK a lot. It is a potent round for hunting, All i have to do is swap out uppers on my AR and I can use my lower and mags "as-is". It can also be loaded in a sub-sonic flavor which I can fire through my 9mm suppressor (Multimount). What's not to like?

I see the .300BLK growing in popularity and staying popular for two reasons:
1. As has been discussed, it is ridiculously easy to swap over to it. Bolt, and mag compatability are huge.
2. It's a great suppressed round. Don't under estimate the rise of suppressors. Sales of suppressors have skyrocketed in recent years as the price of a tax stamp continues to erode. I don't see that trend stopping any time soon. I believe that soon, most gun owners will own suppressors, and hope that one day it will be rude not to own one.
.300BLK is really the best suppressed solution for the AR platform, and that will be the deciding factor in its survival.

The reality is that .300 blackout hit the mark (or rebranded the mark from .300 whisper) in terms of market acceptance.
- Greater punch of the .30 round
-Uses a .30 bullet interchangable with other loads (e.g., 30-06, 30-40 etc)
- Uses existing mags
- Uses existing bolt
- Uses formed existing cases
Basically all the wonders that lead to a low production cost, good performing, easily reloadable round that fits the market. Smart move.
Everything else including my beloved 7.62*39 is a hobby round in the AR platform.

I liked your AR, it just didn't reek of urine and vodka, and make my chest hair stand on end. And my shoulder wasn't sore after shooting it. ARs are cute little guns
Quoted for posterity. What does 6.8 have to do with it? 6.8 has more expensive ammo, requires a custom bolt, custom magazines, does not hold 30 rounds, the military never adopted it, etc.
308 does not even work in an AR15. That is the whole point - 300 BLK works in AR15s.
To be fair, the greater problem was barrel companies making bores that were smaller than SAAMI minimum cross-sectional area.
Lower cost to get into. Brass is as little as 11 cents a case. 30 cal is the most popular bullet size. 30 rounds in normal magazines. Normal bolt. 40% cheaper ammo than 6.8. Also I am the project lead on it at AAC and I know what mistakes to avoid.
The Ballistic Research Facility of the FBI Academy in Quantico VA has completed its testing of Barnes 110 grain 300 AAC Blackout ammunition. They will furnish the test report to any Federal, State, or Local law enforcement agency that requests it, providing that the request is on official letterhead containing contact information (address and phone number). The request must be signed by a supervisor (Sgt. or higher) and the letter must contain the following statement: "The information is requested for official use and will not be disseminated outside our agency."
Your responses are taking my argument completely out of context. What I was arguing against was .300BLK getting 40% of the AR-15 market share in the near term. I was not arguing against .300BLK being a good round, or having a purpose, or even stick around commercially. By all means, I'd like it to stick around and get cheaper. But let's address this from my perspective. 6.8mm was the hotness two years ago. It fizzled out. That is the point of comparison. It is not entirely unreasonable to start there.
Reloading? Not really relevant to market share.
Compatible with existing uppers via rebarrel? Again, also not very relevant. How many people actually rebarrel their guns, versus buying new uppers or (more likely) buying new ones entirely?
Magazines? Well, you got me there. That's a nice feature. I still don't think it's make or break.
So, yes, quote me for posterity. For all of the above reasons, .300BLK will not be taking 40% of the AR-15 market in the next two years. If you're truly the project manager, you'll have the sales projections. Are you genuinely telling me that it's 40%+ of the AR-15 market in the next two years?

Ha! Entirely possible. I really like .300BLK as an SBR and suppressor caliber, and I'm getting into those areas. Believe me, I'd like nothing better than to be wrong and be putting my 30 cents a round .300BLK downrange in a few years.

rsilvers, is the only difference between .300blk and .300WT the cartridge length. What is there to recommend one over the other?

The bigger issue was the chamber & case drawing screwup.
It was bad enough the Remington submitted design had less freebore and a much sharper angle where the neck transitions to the freebore, than the original chamber of the 5th SFG; but if you look at the drawings you can have a conditon where a case 'in spec' to the max dimensions would not fit in a chamber that was 'in spec' to the minium dimensions.
