Lets just say it'll make you forget about shooting your 5.56 anymore. My 5.56 hasnt been touched since i started shooting .300 AAC. And im honestly thinking about selling the 5.56 just because of the lack of interest.

Downside to .300 AAC. Ammo is fairly expensive and hard to come by. So when u find it for a good price, u better buy it in bulk if possible. If you reload you can cut down your 5.56 cases and use them to save on brass.

In a nut shell, the .300 AAC is exactly what the 5.56 should have been from the start.

Good: .300 AAC uses everything from the 5.56 (except the barrel). So you dont need to buy any special mags or anything for it.

WR Moore 06-09-2013 08:53 PM

The .300 Blackout is virtually identical with the .300 Whisper. The only difference is the Whisper used the .221 Remington Fireball case as the parent. Now that .221 case is in short supply (Natchez Shooters Supply lists it, but it's out of stock), people are cutting down .223/5.56mm cases and forming them.

SmokewagonSD 06-09-2013 09:54 PM

I built a 300AAC starting with a S&W stripped lower. I agree with the above post, it makes you want to forget about 5.56.

Hoss0432 06-10-2013 09:20 AM

300 black out is all hype!!! don't waste your money if you feel you need a 30 cal ar buy an ar10.

Blackout and Whisper are new calibers to me. Don't know anything about them. Are they effectively reduced-power .30 cal. rifles, with fire-formed .221 and .223 brass?

If .308 is like a .30-06 Special, is .300 blackout like a .30 Kurtz? :)

Where did you find your stripped upper? I am looking at doing the same for my MP 15...looks like and interesting project.
I am having trouble finding parts.
Any help would be greatly appreciated guys.
Thanks :D

I bought a .300 BLK M&P for hunting purposes. Main reason for purchasing this was the option of switching out uppers if I wanted to shoot on the cheap - either 5.56 or .22.

Also, the interchangability of parts - upper/mags/BCG, ect - minus the barrel - allows for only one platform to support. No need to stock pile a bunch of different mags for different calibers. Gives you pretty much the performance of the 7.62x39 round, but in a 5.56 casing.

Love shooting mine. Put around 100 rounds downrange the other day. Softer shooting than my .270 that I used to have. Even my Dad said the same thing.

Only downside is the ammo is expensive. Cost is way lower if reloading, which is what I intend to do to support this round.

OH, one last thing, if shooting subsonic rounds, makes shooting with a can very quiet. Which is a thumbs up in my book.

oneyeopn 07-08-2013 05:16 PM

I am building a 300 aac Blackout right now off of a DS Arms upper and a Spikes tactical stripped lower. After having my shoulders rebuilt I am having problems shooting my 308's and am hoping that the blackout meets up to its hype.

oneyeopn 07-15-2013 09:24 PM

Here is my new 300 aac blackout, DS Arms upper, Spikes lower, S&W M&P15 Sport Buttstockhttp://i1147.photobucket.com/albums/...ps4e64c531.jpg Matech rear sight, Scorpion Handguard, G27 Pistol Grip, Blackhawk Slinghttp://i1147.photobucket.com/albums/...psd729353c.jpg I use a Lee set of Full Length Dies to form and reload my brass, nothing special to it , in fact you can use whatever range .223 you pick up to make the brasshttp://i1147.photobucket.com/albums/...ps1a3d0c9e.jpg:D:D:D

It's not my Sport but nothing else can be!!!!!

Where did you get your stripped upper, barrel and other parts? I have a Smith & Wesson 5.56 already built and I want to build a 300 Blackout upper myself and need parts source.
Thanks,
Jim

SmokewagonSD 07-15-2013 09:54 PM

I bought my lower in September at the local gun store, which in Wyoming means 60 miles away. Building it up from parts is fun and easy. I got my parts before the panic, CMMG barrel, Yankee Hill free float handguard. One piece of advice, buy the best trigger you can afford.

oneyeopn 07-15-2013 10:03 PM

You can get the DS Arms upper for $350, great reviews.. and any 223/5.56 lower

Woodman90 07-16-2013 06:56 PM

Anyone know where to source a 300 blackout Smith & Wesson upper?

Well according to the S&W website the 300 whisper upper can safely fire the 300 AAC blackout as well.

vipermd 07-16-2013 07:28 PM

Harrison: I have heard good/bad/indifferent about the caliber. I received my SW 15 in 300 W-blk last week, just received ammo , 6:20 pm eastern time. I will have my results in a few days. A magazine " The book of the AR-15 " did a review of approx 10 guns and 6 uppers and also gave historical perspective, and which guns/uppers were working and why. Very helpful. Be Safe,

TRUST8383 07-17-2013 11:22 PM

If you're looking to shoot 300 AAC BLACKOUT, I highly recommend picking up a complete upper from none other than AAC. The components are all top notch and the BCG is a work of art. Here is my 300BLK build.

vipermd 07-25-2013 12:45 AM

Harrison: So far 40 rds- Supersonic- works fine, accurate @ 50, Subsonic- rem 220 gr will not cycle it yet. accurate @ 50. I will be putting the can on, changing scope and moving to 100 YD. More later. Yes I will post targets.

Subsonic doesnt cycle well without a CAN. And alot of times it doesnt cycle well with a mid length gas system no matter how u run it.

Pistol length gas system or an adjustable gas system is the best way to run .300 AAC both subsonic or supersonic with or without the CAN.

If u truly want the most of ur .300 AAC. U need to go a SBR configuration with a pistol length gas system. Shooting it suppressed it has better range than does ur standard 16" barrel. Its just the nature of the beast and the way it was designed.

vipermd 07-26-2013 02:04 AM

What Smitty357 said: accurate, quiet, cycles perfectly with 16" with a CAN. It would not cycle with 220 rem's, and eject only a few hornady 208 A-max. Only out to 100 yds today, BUT , quieter than a 22 lr, my wife had a sub MOA 3 shot group, I tried to stop her right at the trigger break and opened it to almost .5 for 4 shots, then the lightning started, did I mention it was pouring!! I had wanted it to work with out the can subsonic, BUT, I have no problem keeping the can on. Supersonic functions well with or with out. Be Safe,

Glad to see u got it figured out. You will soon find urself forgetting all about the .223, lol. I've shot mine side by side with my .223 and its quieter than the .223. Throw the CAN on it, and you're right the .22LR is louder. Heck even the 9mm suppressed is louder. It's amazing what the .300 AAC is capable of doing the way it was designed. It has always been my opinion that the .300 AAC is exactly what the .223 should have been from the beginning.

Quiet hog killer is what i use mine for. And yes they will go night night in a hurry with a 220GR, lol.

vipermd 07-26-2013 08:49 PM

No recoil, No Noise, 220 gr bullet in a AR size and weight rifle!!!! I will not give up the 308 or 223 YET!, But this is a fun caliber. Be Safe,

RC1 08-01-2013 02:11 PM

Just getting into M&P AR's and have a 15 TS on order. What is this "Can" you mention for the 300 Blackout?

So if I choose to replace my upper later on my TS I should go 300 SBR for better cycling? Does a 16" not cycle properly with most ammo or should I just stick to certain ammo?

Thanks!

johnnymg 08-09-2013 06:13 PM

The M&P Whisper/BO is on my list for 'next gun'. :D. It appears (to me) to be the "best" overall caliber for the AR platform. JMO ~~~~ :p

cheers to all

A standard 16" will cycle supersonic just fine. The problem lies with the subsonic rounds in a 16" barrel. Some are picky (depending on the GR) as another user has already stated. The .300 AAC was designed to be ran as a suppressed SBR. This is where the .300 AAC performs at its best.

I've taken hogs and y0tes with both my 5.56 and .300 ACC. I'll admit the 5.56 stands no chance when it comes to PUNCH. The 5.56 may carry a little more speed, but the impact isnt the same.

The 5.56 is like getting ran over by someone on a bicycle. The .300 AAC is like getting ran over my a semi-truck.

CAN = Suppressor. U will need a tax stamp to possess this and u will need to fill out paper work and pay fees to the ATF. This also will be registered with the ATF to YOU. So the question is, do u want them knowing what u have. =-)

For most people, just replacing the upper with a standard 16" .300 AAC upper is fine. Most people just want a bigger round for their AR15. In this case, it works fine for the job.

If u ever wanted to see what the .300 AAC at it up most potential. THEN, i would recommend going to the suppressed SBR route. The SBR is more pricey as there is paper work as well as fees that need to paid in order to register the SBR. YES, an SBR must be registered with the ATF. So as long as u dont mind the ATF knowing what u have, then u should be fine. Just remember this is the more expensive route, but IMO its also the more fun route.

PS: I still have the above complete upper for sale if anyone is interested. I havent been pushing to sell it much at all though. Originally bought to get my ole lady into .300 AAC. But now she's convinced SBR is the direction she wants to go.

Technically, if you go the NFA trust route (what I'm going to do) the can is registered to the trust, not you.

Correct there are a few ways u can do it. But the destination always ends with you. There is no hiding from them no matter which way u go.

The good thing about the Trust is you shouldnt need ur local Sheriff to sign the paper work. Some people have problems with the Sheriff allowing them to possess such item within his/her county. There are a few more perks about the Trust. But nothing that keeps u hidden 100%

One hundred percent agree with you, that's why I used italics on technically. I feel like any degree of separation is good at that point though.

Smitty357 08-10-2013 10:46 PM

Yep, it allows u to stay a few steps ahead. Better to be ahead than behind, lol

Woodman90 08-10-2013 10:53 PM

A trust will still have a trustee and all the names on the trust are still sent to the ATF. Yes a trust lets you forgo the local law enforcement sign off and no fingerprints or recent photo is required.

Wee Hooker 08-10-2013 11:20 PM

Here in MA a can is out of the question. Still, I liked the idea of being able to get mid range 30 cal performance (similar to the AK/762x39 round ) out of a Ar 15. The 300 AAC won out over the 6.5 cals mainly because the simplicity of the change. No mags to buy, no mods to make, no brass to buy. It won out over an AR 10 because I really don't need to power, punishment and expense of the 308 round.
I went with a quality but no name full upper and a set of dies and am good to go. I never need worry about the cal becoming obsolete because I have everything I need to keep it running and fed forever. I like that allot. FWIW, mine will put 3 shots of PNW147gr into a 1.25' circle with boring regularity at 100 yds. At 415/20 rounds, I don't even find the commercial ammo cost all that nuts should I get lazy in making my own.

My M&P is .300...never fired a 5.56 round out of it...if your knocking the Black out you havent shot it...I make my own brass from 5.56 ..sweet and fun and if you load you can shoot pretty cheap..not like the old days but not bad...Love it

The 300AAC is ballisticly the equivilant to a 300 Savage or 30/30 Winchester. It is not a magic ballistic package, anymore that the 6.8spcRem is.

Nice cartridge, optimized for suppressed work and ok for deer sized targets out to 200+/- yards depending on the bullet/velocity you choose.

Yes, I have one coming...in a bolt gun so I don't confuse the ammo/magazines under stress. If you like it, get one, shoot it and hav fun, it is a great deer dropper and pig smacker.

Smitty357 08-25-2013 09:47 PM

One heck of a suppressed hog killer i tell ya.

By far the best round for taking down those piggies in the quiet of the night.

I actually no longer shoot my 5.56 anymore. unless of course i happen to need new brass for my .300. Once u get use to the .300 and learn how to judge bullet weight for distance. It becomes one nasty little round.

PattonTime 08-25-2013 10:24 PM

300 Blackout
 
I sure concur with most of what I have read here.
I don't shoot my 223 AR's much after buying a Blackout.
It stands to reason though as I also shoot a single shot 30/30 with gas checked lead a lot.
Anyway, I saw that "AIM" has the Mossberg made barrels for $159.00
if I am remembering right.
Makes for a very low cost build, I have a AR Stoner barrel my self , but I noticed the Mossberg barrels are Melonite coated and that should be a nice touch.

SickMAK90 08-25-2013 11:32 PM

I couldn't afford to make it my primary shooter, but I have been considering a 300 blackout upper for white tail use. If it gives 30-30 performance it should be good enough for hunting here in WV. I currently use a marlin 336 and have never had issues taking deer.

nitewatchman 08-26-2013 12:46 AM

Could or can the Blackout shoot a cast Gas Check Bullet or could this lead to potential gas system problems?

Aside from being dirty this could really offset ammo costs for casual shooting.

nitewatchman

oneyeopn 09-29-2013 02:37 PM

Ok..I have had enough time with my "blackout" and she is a shooter, there is a lot of discrepancies in the reloading data and improvements happen all the time. I myself am testing some hotter supersonics today, rounds that I want to use for hunting When I say hotter I am talking 2400fps MV. LOL I still prefer to shoot my Sport....I think I always will but I love being able to shoot the wings off of the housefly down there on the gate post...
http://i1147.photobucket.com/albums/...ps07db3c92.jpg
Here is my 300blk as she runs, she is a great offhand hunting rifle. She really shines in just shooting. All the different 308 caliber bullets to choose from plus mine runs Commercial Whisper loads just fine (they are the same reloading dies). Mine also runs the commercial subsonic ammo and cycles them also but because I have no desire to shoot subsonic ammo I do not think much about it.http://i1147.photobucket.com/albums/...psb7de6b24.jpg
I keep her on a diet, that is an old Westernfield 4x33 scope and it works like a guide scope which is what the first guide scope actually were. The UTG Pro handguard is light, customizable, I love the fit and the fact that it covers part of the upper receiver to make it more seamless. That is the ATI pistol grip which is a copy of the G27 by first Samco which I have put on 4 different MSR's and am glad to find someone else making that style. I have a pretty complete set up of extra's that I can put on or take off quickly if the situation would require. It also is my deer rifle this year. But at 8.2lbs(with 8rounds/pmag) is actually heavier than I thought but is a great little rifle. I am glad I built it, but out here on the prairie my next project will be a 24" varmint barreled MSR.

You can shoot a gas checked bullet or there are companies making harder cast bullets for them...the powders used in the blackout dont seem to burn as clean and the rifle gets a bit dirtier. I quite cleaning mine about 50 rounds ago just wanting to see how long before I get a problem because its too dirty....My Sport seems to go forever!!!!;)
I shoot cast in some of my guns....but there are tons of cheap jacketed and plated ammo right now in .308....a lot of guys are shooting pulled 147gr Nato bullets....they are cheap and they shoot real well out of the blackout.

Having just finished my long range 5.56mm project build (other than optics), I'm already starting to source parts for a .300 AAC Blackout project. Should be fun...

I'd have posted my build parts, but since its based on non-S&W components, and we don't have a non-S&W Black Gun sub-forum...
