In the early 80s, 1983 I think, J.D. Jones of SSK Industries developed the .300 Whisper for the EXACT SAME purpose/concept (Subsonic/Supersonic cartridge fired from AR type platform with supressor) as the .300 Blackout. It was being done way before ya'll "discovered" it.

It could be called a rip-off but Remington isn't the first to emulate it. They are, however, doing a far better job of marketing it. Personally, I'm glad Remington is doing this because this awesome caliber is becoming more affordable for those of us without bottomless pockets.

This cartridge is from 1969 - 5.56mm shortened and opened to 30 cal - done for the Colt IMP PDW:

SSK did a good job at keeping the concept alive, but JD did not invent necking up a 221 Fireball to 308. The 300-221 and 300 Fireball are older than that. What he did come up with was the name "Whisper(R)" and he certainly owns that name and the brand.

Here is a document from 1977:

It does not eject but the shells move out about 1/4 inch and then you pull them out easily.
 
Who is making blackout ARs?
I fired a CMMG .300 blk last week. Full auto, suppressed. Thing sounds like a laser gun, it was pretty awesome I have to admit. Who is actually the market for these things? Aside from the guy that has to have it all?
 
Three unsafe rounds of Hornady 208gr 300 Whisper at 100 yards...

This rifle has survived in the neighborhood of 5000 unsafe rounds...who would have thunk it...

Fun so far

After reading ALL of this thread, it seems the detractors are fewer. Which is good, before I was going to pass judgment, I wanted to shoot one. I did and it's likeable.

I have been curious about this round since I first heard about it; About the same time I had purchased a AAC 7.62 SD can for one of my bolt guns. I've never really been a huge AR fan (sorry, like bolt guns); however, I can also appreciate the usefulness of having an AR around for practicality and they are just fun to shoot.

I built the least expensive set up I could, as I wanted to try it before making a huge commitment. This consisted of a $219 AR Stoner (the cmmg was cheaper but had less praise) 16 inch, 5R stainless barrel and an $99 AAC Brakeout muzzle device from Midway. Took about 30 minutes to assemble on an old $300 DPMS upper that I wasn't using. I bought 100 rounds of subsonic that a dealer had in stock here and headed to the range to form and opinion.

Without the can the subsonic is handgun loud and pretty accurate. If I had to defend my house I'd much rather shoot this in a hallway that a full pop 5.56. The sound of the impacts on the berm demonstrated that this thing hits like a truck (I'm gonna go shoot a few more things (stumps, melons, cans etc) to see what kind of truck)

With the can well now, that's a hoot. Without ear protection I can hear the bullet strike the target and the impact berm. Running the gun, all the ruckus the gun makes kinda spoils the quietness so I gave it to someone else to shoot. It sounds like a healthy pellet gun and still hits like a truck.

I've yet to try supersonic (loading it this evening) but so far so good.

I still like bolt guns (ordered a 300 BLK Savage barrel ) but the fact that this thing uses relatively little powder means I can shoot more and it's fun, I'd say it was worth the $300 odd bucks to give it a try.

More on point, does this have a useful purpose? for others, I don't know for me it's a chance to use up the 2500 SMK 220's left over from a failed long range bolt gun project (I tend to be excessive) and blow up some pumpkins with some 110's. In fact it's a good way to dispose of all of my 30 cal left overs from years of competing with a .308 and 300WM. It's the only .30 I have at the moment :)

It has enough usefulness for me to send off a form one and pay a gunsmith buddy to take a little off the end when the stamp gets back. The can on a 16 inch makes 50 yard shots a breeze you just lay the muzzle against the target and squeeze.
 
Nefarious, glad to hear it because I just ordered the same barrel and am doing a similar upper build to play around with this.

Robert, I think this caliber could also really use an affordable (sub-$400) 16-18" barreled bolt action rifle built on a .223 length action (or perhaps Remington's 7615 pump) with a conventional style stock with removable spacers to allow one gun to fit youth, women, and adult men. That could make an excellent starter deer rifle (for shorter distances) and multi-purpose handy woods rifle for larger varmints. The muzzle could be plain crowned or threaded with a thread protector, obviously the former is going to be cheaper. Just a suggestion for something you might suggest to the Freedom Group bigwigs.
 
Savage probably will when they get caught up, they are selling everything they build at the moment and are pretty good at making things just interesting enough that people will buy them. They have the Honda motorcycle marketing strategy "you think what you got last year was cool, wait 'til you see this" and they are very quick to gauge what their customers want and make those things available.

It might be a conflict of interest but AAC should make some drop in Savage barrels.

Savage enthusiasts are well known tinkerers and barrel swappers. I'm a savage enthusiast and I have quite a few extra barrels in calibers that raised curiosity. $200-300 just to check something out is way more palatable than $800 plus all of the requisite "things" to investigate something that might be fun.

BTW, I handled the new AAC bolt gun today. I like it. Good call on putting the rail on from the factory, it's one of those little details that can be really frustrating when you get a new rifle.

Also, kudos for having the new bullets pointed, saves me the trouble.

Savage should do one - they have a low cost bolt action.
You've already shown us the Micro 7, and the prototype H&R Handi Rifle in .300 BLK. Why not a Marlin XS7 in .300 BLK?
 
I was thinking about the new Mossberg MVP for this. It is made to use AR magazines, the .223 bolt face will work with any of the 300 Fireball/221/223 variants, and it should be a pretty straight forward barrel change. However with a suppressed Ruger 77 in .308 I just don't have a need for it...

doesn't stop me from giving it some serious thought tho.
